I think family loyalty is deep rooted, where as socialism is something people debate (maybe more a mix of neocortex I.e. planning and lower emotions coming from morality and political identification)

No matter what their politics most people will look out for their family especially their kids.

I would say there is a high socialist elements - a parent doesn't have to sacrifice their economic comfort or even time just to give their kids a better education or better lifestyle. But many do so.

I completely agree. I am not suggesting actual socialism, which has failed spectacularly.

Added edit to clarify.
