You are very much dependent.
Whats the difference between me, working in tech, having a good job, great money and being able to put everything i earn in my own land and become independent with something between 40 and 50 versus you? Stoped working, doing small jobs barely making it, not having any money for any sustainable development on your own?
If you are not doing it, everyone else will do.
Either you understand and accept that the world is going to look different in 50 years and you are ready for it with the minimum footprint you need or you go more extreme to try to change something.
And even if you do know that you might not change the world, if you would sacrifice for the society, the money you would earn in tech would allow you, as a single person, to funnel the money from the economy where you want to. You would do more good then tthe other person who is now doing your job and who is just spending and consuming it somehow.
And just to clarify another thing: In tech you are able to go to your boss and work half time and even then you would have more possibilities then in any other job.
