Mine are all moved out even though my youngest is 22. I'm actually for young adults living with their parents as long as they're working and saving and investing for their own place. Two of my kids did that, with them showing me each month how much they were setting aside. One of my kids moved out early on his own ambition. Only one had to be told after high school to either work and contribute or get out.
But we're weird. Most families aren't doing that. Combine that phenomenon with the baby boomers retiring in droves, especially with the china virus accelerating an already big retirement phase, and there's a yuge shortage of labor.
I retired before covid. There are a lot more people playing weekday golf now than before covid.
