> If everyone is sociopathic, everyone is worse off. In the world of sticks, stones and endurance hunting from which humanity evolved ... this would be true. But recent centuries' economic artifices have made a mockery of it; insofar as being "pro-social" has ceased to be necessary to produce generally-valuable things nor to trade the generally-valuable things for a specific basket of things that are valuable for one's survival. Generally, modern technology and economics have changed humanity's environment much faster than we can evolve to adapt to it; otherwise, (for example) either Coca-Cola wouldn't be addictively successful, or our brains and bodies would be less stingy with energy (and therefore better in myriad ways).
