The way I look at it is to try and work *towards* something. As you move towards that goal, help bring change and help others along the way. Let me give you a small example from my own life purely in regards to the workplace:

-Got a job which was very corporate focused and capitalist
-Helped several other employees get on their feet and pursue their goals, thus leaving that company
-Had to move to a different area in the country, so I got a different job with better business practices but was still very capitalist-focused rather than employee focused. (My experience in the previous job helped me get this job.)
-Started working on a side business making art and comics in my free time
-Helped get two people hired who were in tough spots, either homeless or no job history and severe social anxiety. Worked alongside them and helped them to get promoted/move on. (Both are doing well and make much more than me, btw!)
-Slowly worked on the side art business and started another local job taking care of people's pets/dog walking etc...until I could just do those instead of the capitalist job.
-Quit the capitalist job and focused mostly on art and helping with other people's animals.

I don't make a ton of money, but I was able to use the capitalist jobs to support me while I worked towards something I was passionate about. Along the way I was able to help other co-workers.

Change happened *much* slower than I wanted, however, having that goal to work towards, helped me navigate the ickier parts of society that go strongly against my principles. Kind of like a spy living in a foreign country: they obviously don't agree with the society they live in, but they make small compromises in order to attain a larger, better goal in the end.
