Discounting the counter productive condescension required to be the one putting the other guy down, we should all be honest with a simple fact: any typical software dev (just talking about what I know) can succeed at a gas station job while the reverse is not true. This obviously does not afford the software dev the right to be a jerk to anybody (up or down the ladder).
Intelligence is only one of the many variables needed to succeed in certain occupations.
Although you have zero supporting evidence for this fatuous assertion, you're perfectly fine with passing it off as empirical data. If you actually took the time to speak to your average software dev particularly in America, you would find that it's more likely that they've worked customer facing retail when they were younger. These are pretty much the only types of jobs that are available during high school. I myself have worked at Walmart, Blockbuster video, Chick-fil-A, and as a landscaper during the summers. None of it was particularly taxing - although it was extremely tedious at times and often boring.
And while we're on the subject of anecdotal data I would say on the order of at least 60 to 70% of software devs that I've worked with in the past were actually in relatively good shape physically and usually were very conscientious about their diet and maintaining regular exercise.
We really need to be filtering people back to Reddit.
But I do think the world is a better place with more "CEOs" running independent taco joints, and less Tacobells.
Nothing wrong with working for someone, that wasn't my claim.
That's the whole point of the matter though, isn't it, that if you don't have ambition, then you voluntarily get yourself stuck in a rut of your making. "I'm content in that my life is shitty in X or Y way, but cannot do anything about it".
There was a time when I found comfort in thinking that I would grow up to be "comfortably middle class". My parents disabused me of that notion, and now that I am at that stage, I feel as though there is so much more I can learn and do, instead of clocking in and out day after day.
But hey, if you find happiness in working at a gas station or something, maybe you are more enlightened than I am.
