This is why people critique the nuclear family—the degenerate village around the children that just consists of the parents, maybe grandparents at holidays. It’s a recipe for overworked adults.

I've got a Mexican American friend that lives multi-generationally and loves it. He's a few years out of high school with a good job in management and a nice car, money in the bank. His older brother gets help parenting from Tio and the grandparents, and generally everyone gets along well. He's almost kept up with me in savings for property and I'm married (our pay is pretty similar, but I have dual income). American culture optimizes for wastefulness and puts too much of an emphasis on independence, especially when arrangements like this exist that actually can lead to greater individual freedom in the long run.
