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.
I've been homeless. I didn't find that fulfilling or rationalise it with some Zen monk shtic. I saw it for what it was.
Anybody who is part of something greater, and who has learned to not depend on various addictions, wealth signaling, etc for greater fulfillment. A lot of this is in the mind, and really just a matter of adopting healthy perspectives on life.
