This is absolutely it. You can't get the weird, good and bad, unless your cost of living is so low that subsistence can be met with minimal effort. That free time is necessary to do acid and work on the crazy stuff that people don't understand, yet.
I, a millenial that pays $2k/bedroom, am always struck by the portrayals of the 1960s where people in their 20s live 10 to a loft and make rent working a few nights a week at the bar downstairs.
