i saw alot of posts elsewhere about this, especially after the layoffs(living at home laid or graduating ripe into layoffs still at home, boomer/gen x parents whining jobs should be open left and right, and apply). plus it somewhat more common in american to force your child to leave home after 18. its mostly HCOL, and job market being plague AI screening is preventing people from finding jobs these last 3-6years.

and yes milleneals are essentially supporting boomers into thier retirements, some of which they wont get when they come of age. and genz were seeing the beggining of them being under-employed due to layoffs.
