Is it because:
'Women often form relationships with older men. Between 24 and 30 a chunk of women will have children/form households with men aged 29/30 plus.
Social conditioning leading to men being less independent.
Men being conditioned to think they will be expected to provide financially for a family in their 30s and thus choosing to live with parents to save a nest egg towards this.'
From my personal experience in real life this seems like the reason most guys still live with their parent.
Low wage younger women seem to still be able to maintain and gain solid friendship group and get dates frequently.
Low wage younger men I know that do not live with their parents are most likely to be loners and end up having a lot of issues such as alcohol and drug addiction.
It is unfortunate that a lot of young men in lower end of the social/economics class do not have the options of living with parents to build themselves up.
