I think it's almost impossible unless you start a business yourself and run it without hierarchies, and with everyone involved being treated as as an end in themselves and not just a means to increase the company value. If I ever make enough money (unlikely), it's a quiet fantasy of mine to start a small company in this model.

Personally I will never work in e.g. finance or "defence", but even where I work now could be seen as encouraging throw-away consumerism. It was a very serious consideration of mine when I was looking for a new job. I ruled myself out of some interviews halfway through because I could tell that their product would have rubbed against my morals eventually.

Sometimes I feel like a mug for following my convictions like this. I will never be a manager, I will never invest in the stock market, and I will never own more property than I can use myself.
