Are Teens & under 25s having their development into adulthood retarded so that they dont grow up until age 30?

There is a theory that kids and young adults development has largely been retarded. I mean I've talked to so many college kids that are frankly so immature and its obvious their development has been retarded. That is they dont behave as responsible adults, especially since they are in the hole litteraly for tens of thousands of dollars or pounds. They dont know how to look after themselves, wash a dish, do laundry, work a crappy job etc, parents will solve all their problems and pay all their debts while they play Xbox or work on their careers as social influencers/digitalcreators. Life's too easy at the Hotel of Mom& Dad.

To retard something means to make its development or progress slow; hinder or impede. (E. g., "The lack of rain will retard the growth of the plants").
