Going back to your original argument. If you don’t have a genetic tendency towards antisocial personality disorder, it’s less likely capitalism will make you callous.
However, if you do have those genes, they’re more likely to express as antisocial in a culture like ours.
So it’s both the individual biology and the environmental factors.
I used to use sci-hub. I forgot about it today. A lot of stuff has become more available. I think studies done by or funded by the government are all open access now. I might be wrong though.
I was trying to find a study they did on Netherlands criminals vs U.S. criminals. They found the former more rogueish and the later more callous. Could be genetic or environmental causes to this. Maybe Danish people are genetically less callous. Or maybe it’s the culture. Probably a combination of both.
