Isn’t there some optimization point where you grow your wealth and status throughout life, presumably using the machine of exploitation, then at some point begin “paying it back” through means such a charity, helping around your community, or (depending on how well you did) exerting industry or political influence for change?
I find it hard to believe opting out of the economy is the best way to foment change, especially when there are so many out there without any such scruples, happy to scoop up what you’d carve out for your ethical ideas.
