Why do so many men get away with being failed adults?

As both of my parents have jobs, I have learned to do all house stuff by myself from childhood from cooking, cleaning to sewing to almost everything and I manage to get high-quality education too. But it's so hard sharing apartments with almost any guy. They oversleep, drink and vomit and never clean up. They leave food everywhere with and messy kitchen. If you tell them to clean, they will most likely shame you for being not so manly or like a girl. Guys in the military are considered highly manly but they do all of their work by themselves while maintaining their jobs.
The worst part is girls like that kind of behavior. I have heard many of their girlfriends saying that they love it and are so excited to live together where they can take care of their guys.
