Collectivists just want to be left alone? How does that work?

It's pretty simple, they just go about their lives. How exactly do you imagine collectivists live? People in a collectivist culture or society aren't attached to each other by the belly; as long as their culture/society is functioning they probably would want to be left alone like any regular person, collectivist or not.

Yeah in fact, from my experience you're more likely to be harassed walking down the street in the USA where the poor are forced to take to the street as hawkers than in Germany where you can still carry some dignity.
