I think there is a strong common causality between beating up of nerds, prohibition against porn, and prostitution, the setting of child support proportional to a man’s wealth, income tax, and anti antisemitism.
They all aimed at those most “talented” to hide/destroy their advantage.
nerds->smart->get beaten up
porn->pretty-> you need to hide your talent
prostitution->rich->can’t just use your money to get laid
income tax->diligent->Nope y ou can’t keep your hard earned money
child support laws->rich->no body can afford more than 5 kids no matter how rich they are
jews->smart, rich->what happened to them?
I think you should read all the other answers first. Like Eric. This is for the cynical:
It’s the cynical answer. I know. The more ethical answer is because it’s “fair”. However, for how “fairness” somehow becomes reality requires a little “process”. Fairness, is not just moral. It’s practical, and profitable. It took times for us to realize it, but we finally did.
The basic idea of is that under capitalism, people get rich through productivity. So it doesn’t matter how they get rich, they are benefiting everyone else.
