A lot of young men still live with their parents for the simple fact that they couldn't survive otherwise. Car insurance alone take two pay checks let a lone gas and a car payment. Plus you have ever increasing rent and utilities. Add in mandatory health care and food plus any amenities. There are some grown men living at home because they are just lazy yes it is true. But the majority of young adults live at home because it is impossible to survive anymore. And the younger you are the more expensive things get.
