First of all, we do our evangelical work everywhere, to both rich and poor individuals, but in general people who are poor or immigrants or minorities are more interested in religion when compared to someone who has a high paying job and feels they are already very satisfied with their life.
Second of all, Jehovah's Witnesses advocate a simple life. The idea is that it doesn't take a lot of money to live a nice life, its how you use that money. For example, a baptized Witness is not be a smoker, gambler, alcoholic, etc. By quitting the smoking or drug habit many individuals have lowered their expenses, allowing them to live better lives without raising their income.
To some extent the pursuit of high education is not encouraged. Although many Witnesses will get an Associates Degree, it is generally not encouraged that they go on to higher education. This does also limit income.
But to go along with your comment, yes I feel happy and fulfilled. I spend roughly half my time at the computer doing freelance web development work or working on my startup Bookflavor. The rest of the time I spend with friends or doing door to door preaching. It is actually very interesting.
Imagine going door to door one weekend in an affluent neighborhood where a security guard takes down your license plate before allowing you to enter, then the next week going door to door in the ghetto where you have to watch where you step to avoid trash and used condoms. Jehovah's Witnesses get to talk to people of all sorts. As someone who is deeply interested in psychology and sociology I enjoy this communication with people from different cultural and economic backgrounds. Our door to door work is fascinating not only from that perspective, but also from the perspective of practicing real world sales skills. I would dare say any decent Jehovah's Witnesses would make a great salesman/woman.
I would say that my life is very interesting, and I wouldn't be any happier if I worked more hours so that I could make more money. Indeed if I worked more hours to make more money I wouldn't have time to work on my startup.
I want to ask you a question, why do you feel the need to go into someone's house with the goal of converting them to your religion? I've had discussions about religion with a few Jehovah's Witnesses that have come around my home, and they've been resentful and insulting when having to deal with a two sided conversation about their religion and my lack thereof. I'm of course not saying you're the same, but from my experience, most Jehovah's Witnesses seem either fanatics or 'salespeople' (people with the need to make me buy into something they want me to).
I have a problem with being disrupted in my home after a long day by someone trying to convert me into a religion I don't follow, but even then I try to be respectful and understand that people have different believes to mine. I'd expect the same treatment from a person ringing my doorbell to preach, but I have found that it very rarely is the case.
JWs believe that all other religions are tools of the devil designed to distract people from the one true religion - theirs. This is true of "false Christianity", other Christian religions, as well as "pagan" religions. Being a good JW is the only sure way of staying on the right side of the JW version of the blessed and the damned; belong to any other religion and your chances aren't so good (though God may give some people a second chance after he destroys our world as it exists today).
On a more practical level, there is immense peer pressure within the church to go door-to-door. Hours spent evangelizing are reported to the local elders by each member of the church and detailed records of evangelism activity are kept. Families and individuals that don't spend sufficient time evangelizing are pressured by the church elders to do more.
To make this easier to understand you could easily substitute other goals. For example, what if you knew of a treatment for diabetes or AIDS that could benefit others? Wouldn't you feel the need to tell others with diabetes and AIDS rather than leaving them to stumble across it on their own?
Likewise, we feel that the morals and lifestyle we advocate are beneficial and can help many improve their lives. Therefore we want to tell other people about it. At that point other people can either say "I don't like it and don't want to hear about it," or "I like it and want to find out more."
I'm sorry you have had some bad experiences with Witnesses visiting your door in the past. Naturally there are unbalanced and insulting Jehovah's Witnesses just as there are unbalanced and insulting atheists. People differ. However, I can assure you that every Jehovah's Witness is encouraged to be very respectful and polite about sharing his/her beliefs and listening to the beliefs of others. Some people's personality traits aren't up to par, but we can't stop them from going out and talking to others. Remember that every Jehovah's Witness is a volunteer so naturally some of these volunteers are going to be good, and some of them aren't going to be so good.
If you experience someone who seems rude or confrontational you can tell them to leave your door, or you could get their name and complain to the local congregation (using the phone number in the local phone book). Somebody will probably talk to them and ask them to please be more polite.
At any rate if you would like to try a decent, two sided conversation about religion or the beliefs of Jehovah's Witnesses feel free to contact me:
My issue is that more times than not, my answer tends to be followed by a list of why I'm wrong and why I should convert. If I expressed that I'm not interested in the discussion at that time, I'm bombarded with reproach. If it happens that I'm in for some friendly debate, it becomes an issue of being told that I'm wrong because god said so... followed by more intense reproach, of course in a not so friendly way.
I'm generally not a fan of discussing religion because there are no clear cut winners and it generally becomes an issue of the more eloquent party having the upper hand. More times than not someone ends up with angry-ish feelings towards the opposing party. In any case, you're probably a diamond in a sea of carbon... You guys should make door to door preaching something a member can do after being vetted as capable of not offending the population you're trying to convert.
Perhaps if you were willing to talk about your beliefs I might go on to other questions such as "Do you believe that it is possible for us to determine if a God exists?" or "Do you think it is possible to find evidence that God exists?" and "Would you be willing to listen to some reasons why I feel that there is a God?"
If so we could discuss each individual reason. Really it is comparable to having a discussion here on Hacker News. There are disagreements here on HN but as long as everyone sticks to the guidelines everyone involved can have a productive conversation. I feel that likewise it is possible to have a productive conversation about religion.
Jehovah's Witnesses do have a vetting approach of sorts when it comes to determining capability but as I'm sure you will agree vetting is an extremely hard problem to tackle both accurately and fairly.
When I was around, they did't have the wealth or intellectual sophistication to advertise themselves effectively. We had been using the same sales book for years and I wouldn't be surprised if "the reasoning book" is still around. An organization that enforces orthodoxy as thoroughly as Jehovah's Witnesses isn't exactly a breeding ground for creative and entrepreneurial spirits.
I wouldn't expect them to pivot if hard sales techniques proved to be annoying or ineffective. They used to publish their conversion statistics in the January 1st or 15th edition of The Watchtower so you could follow their growth (an anemic 1% or so per year back in the late 90s). That was a shockingly transparent move for such a close-minded organization; it probably helps increase members trust in the central organization. But it is also bad for morale to watch numbers languish.
Universal evangelism in JW congregations will never disappear. The shared experience helps separate them from the rest of the world and bind them together, much like hazing at a fraternity or combat experiences in the military.
As an unbeliever growing up in a JW household, going door to door every weekend was certainly one of the most horrific parts of my early life. I am so, so glad that is over.
My experience is mostly with people who had the misfortune to be born into the church who live repressed and desperate lives. On the other hand, most converts come from the rank of the poor and destitute and probably see their lives improve upon joining the church due to the strict lifestyle and strong community.
The poverty of Jehovah's Witnesses is mostly due to the forced ignorance of their young, since there are so few converts (at least, US growth numbers were poor in the late 90s/early 00s, probably below member fertility).
