Is it a form of welfare that can be counterproductive or is it better to let kids stay home for as long as possible? Each person, each child, is different, so you should take it at a case by case basis. Generally, as parents, you should treat your kids as grownups when they're grownups. You probably should give them the rules as they grow up, gradually, and when the time comes, charge your kids some rent that can either be payable financially, via money, cash, cryptocurrencies, or compensated by labor, work, services, chores, duties.
