"Wow, do you have any idea how many open source software contributors are living on Ramen and are on the side of the working class?"
Maybe those types are eating ramen because they aren't getting paid for their work? There's a thought. In some places if you get caught doing that while on unemployment benefits, you will get those stripped from you too.
I don't like our economic system much either. It's run on creating debt. You have to have money and support from elsewhere or you sink.
Or maybe they choose a simple life because they find greater fulfillment elsewhere. Like the feeling you get when you're part of something greater than yourself.
