Well it's blatant propaganda. Think about it, when people got rid of kings and 'nobles', they didn't take the wealth from them. Those people stayed rich and invested that money into business. The ruling class never changed, they just changed job titles.

There has also never been a system (under capitalism) where peoples wealth is taken from them when they die.

The whole idea that under Capitalism everyone "Starts from 0" is just laughable.

Capitalism was never a punishment for nobles who didn't work, it was a way for them to continue to stay in power, and still not have to work.

The vast majority of wealthy people were born wealthy. The vast majority of people who start from 0 will die with basically 0.

Adam Smith himself was born wealthy.

Very occasionally, someone like a Bill Gates or a Steve Jobs will come along and be successful, but they are the exceptions to the rule. And most of their wealth came from exploiting people.

A few professions could be a path for poor people to succeed, like for example Lawyers, but you have to have the money for Law School in the first place, so most of them came from well off parents.

Capitalism wouldn't exist if it were a fair system.

Just like the Bible, no one actually reads it
