That's not what he's saying. He is saying that your father and my father shouldn't be supremely unequal. Ie your father being a CEO and earning 10s of millions every year and my father working a product manager role at a small company.

Very often there is a huge factor of pay difference between roles like these.

Let's ignore CEOs.

In my parents' generation it would not be absurd to buy a small house here to raise the kids in, with a single parent working and the other caring for the kids, even if you don't have a well-paying job. A decent job will do.

Compare to now, double income, no kids, both earning above average wages. Buying a house before you are 50, or at all? Forget it.

Just that those people who inherited the house now basically have enough to buy 2 houses out somewhere on the countryside if they decide to move.

What if the CEO wants to make 10s of millions to ensure he can support his family for generations to come??

Not sure if you're trolling but otherwise genuinely perplexed by how you could draw this conclusion from the above post.

I think it’s pretty clear, a system where a family can’t guarantee their offsprings success is one where the family is unable to do anything to improve their children’s fates.
