Food and water can be quite cheap: the grocery stores are filled with healthy foods you can get for less than 1$ per lb in most of the US: corn, whole wheat flour, bananas, apples, grapes, onions, beans, rolled oats, etc.
The biggest problem with living cheaply is Housing, Healthcare and Tax. for the most part these are mandated by the gov regulations to be really expensive. Once those are solved, we'll be able to live quite cost effectively. I've seen some people get around that by living in a camper van, traveling the world - not for everyone, i know. But, the tiny house movement shows us we can get a tiny house for just 20K.
Also see, the resurgence of Hookworm in Lowndes Al.
"I am so dedicated to my work that I willingly turn my home and outside-of-work life into the smallest possible monastic box, using less resources than the average Joe. Plus I'm so classy that it's a beautiful box, and it can't be cluttered by bourgeois garbage because my experience outside work is a stark void and doesn't generate things that would require space."
Whoa, that looks good on your performance review. All you need to add is 'and I'm never there because I work all the time. The only person who sees my house is Merry Maids, and they only have to send one person with featherdusters all over her. She twirls, and that's her job done for the week' ;)
What you are suggesting would lead to a generation that saves more and consumes less.
When GDP seems to be the only success metric that matters, I often wonder if such education is omitted intentionally.
So taxation on a massive scale doesn't work. The problem isn't that the super rich are too wealthy. The problem is life is too expensive for most people. That's the problem we should try to address. In order to do that you'd have to reduce the cost of housing and healthcare.
Funny how that importance is never 'serving people the best way', and is always 'thousands of times more powerful and wealthy than you could even imagine and consuming the blood of young servants in order to live forever'. With some of the most successful Silicon Valley capitalists, the latter is literally true: consuming the blood of the young in hopes of living longer.
I'm not sure how much more on-the-nose it can even get. It's kind of nice to see these things openly talked about. It's legitimate to ask, "This is possible, indeed is happening. Is this good?"
I myself, went to the cheapest college in my area, even though I could have gotten into a far more expensive/prestigious college. I chose not to because I knew it would put me a great economic disadvantage to have so much debt. Software engineering careers and many other careers don't always benefit from more prestigious schools.
If more people shopped for colleges based on price then maybe universities will start competing on price and we can finally see them planning ways to make college cheaper instead of adding yet another good for nothing expensive wing to the campus.
