In 500 years there will be fewer radicals than today as a percentage of the population. Fewer humanitarians. Fewer communists. More greedy scum. More sadistic monsters.
Until one day we are all no more than the beasts Capitalism already treats us as.
False premise. That might be true for a small set of the population. They are small isolated populations that often inbreeds. I have often wondered of there were special things to know about medicine for the royals for example. They probably have a very specific set of genetic traits a doctor would have to look out for.
However for the rest of us without capital being extra capitalist does us no good. Being kind and working together with others is actually much more beneficial for us. So there would be no pressure there.
