Student Looking for Help in Field

Hello!

I'm a CS student, have been a FOSS lover for a long time and am a commie since recently (a year or two). I was thinking of my future career and as much as I'd love for there to just be an easy, free and open approach to using my skills, capitalism just makes it all impossible. I know thay capitalism will make it impossible for me to exercise my profession in a good way, but is there no alternative that fits in the middle anywhere?

There just seems to be for profit software if I want to actually get a decent wage and a decent life. How can I get a decent job with free software? The idea of it just inhibits it while on the capitalist mode of production.

TLDR: how can I be a FOSS dev while not caving to the interests of big techs and corporations to provide for myself (aka be a hypocrite)?

Thank you for your time reading, cheers from Brazil!
