I am in the same boat, got into tech lead position for more money. As a tech lead, I have 0 power and a lot more responsibilities. Hate it.
I tried to go back to dev position but management kept blocking it. So I have been practicing leet code and hoping to go to one of FAANGs. But maybe freelancing is a better route for me. Only thing is that whenever I look up freelancing rates, they are quite low compared to my current average Texas SWE salary.
If you want FAANG money, just join FAANG.
If one likes to work in Southeast Asia for example, it doesn't take FAANG money to enjoy living there.
"looking up freelancing rates" is almost ... impossible? Most places I see that offer that are self-reported numbers, and I don't know who's self-reporting. Freelance is going to be largely what you make of it, but there's definitely a 'sales' aspect to it, at least periodically. You need to connect with prospects, demonstrate ability, set up a deal, get paid, do the work, get more paid, etc. It's not impossible, but definitely takes a bit more work for many folks. Word-of-mouth referrals helps remove some of those steps. Finding another agency to work for/under can help too - they can handle some of the 'finding work', and maybe even billing, but they're going to take their cut. May or may not be worth it - you can definitely get more flexibility, but that's not everyone's primary goal. And... with the pandemic, most people are remote working now anyway, and have some more flexibility than they had a year ago, so there's a bit less obvious win there as a comparison point.
That's the problem with quick Google searches and not living and exploring job market in the given country. I agree that there are truly a lot of developer jobs in NL paying in 40-70k range. However, there is non-exceptional number of jobs paying above that.
I won't name the company I am working for, I will just outline industries which offer 80-120k+ here in NL: obviously, FAANMG; financial institutions; hospitality; healthcare. And most probably a number of others that I am not aware about.
Also there is quite a discrepancy in pay among companies even in the same domain, so generalizing is difficult. E.g. I used to work in TomTom and I know the pay there is in 40-70k range. However, I cannot say that it will be the same for e.g. Phillips.
It IS that, money wise, in all the places where even the best employed developer does not even make close to 100k, e.g. all of Europe. Which is why a lot of managers in IT suck. They are previous developers that reached the developer salary ceiling. Then you can only become architect or some kind of manager.
