I think you're forgetting (or deliberately ignoring) all the great political and economic frauds that have happened in capitalist systems too.

I don't think any political/economical/social system can ever be immune to fraud and sociopaths.

It’s true that fraud and corruption will always exist but it’s also true that it’s less prevalent in a capitalist system because it’s more (not completely) transparent than any other system that has been tried by humans so far.

You actually think the political class is not full of thieves anywhere else?

It's a career path that attracts this kind of people, like flies to shit.

I am calling countries in which communists are no longer the political class, but even when turned into a social underlayer class, these fellows, and their offspring, or even their grandchildren cannot vean themselves off economic parasitism, and economic crime.

They are becoming a multigenerational class living off economic crime.

I can't help but laugh because your last line perfectly describes inheritance, a practice whose abolishment was demanded in The Communist Manifesto.

Yeah, I often hate doctors myself. Doesn't mean the majority are bad.
