Yes, conservatives are INNATELY more critical of free-riders:

“North Eurasian and Circumpolar hunter-gatherers (Hutterites and Amish, Puritans) will be more prone to altruistic punishment than those from Middle Old World culture area (Jews, Gypsies, Chinese)”

“…. *** Puritan groups seem particularly prone to bouts of moralistic outrage directed at those of their own people seen as free riders and morally blameworthy.***” -Kevin MacDonald

Whether it is cultural or genetic or both doesn’t matter so much, although I’m in the 60/40 camp in favor of genetic on this topic. And the pareto rule would suggest that as long as you’re in a 90/10 proposition or less, diversity isn’t a problem.

But two things are certain: a) people don’t actually assimilate outside of their gene pool, and b) our tribal differences – our tribal DIVERSITY is something very precious for everyone. Probably the ‘cuircumpolar’ in particular. Because that individualism is economically superior to group-ishness.
