I did a bit of mild googling.

1% of Americans control 30% of the wealth of the nation, and apparently 12% of property.

It's more than reasonable that people with that much wealth to their name pay the vast majority of the taxes, as it used to be.

From a nation building perspective, there's no reason to allow a couple hundred people to wield 52,000,000,000,000$ worth of assets. It means the economy has gotten far too clumpy and needs some redistribution. This isn't even really all that anti-capitalist. Capitalism can't survive long term without budding up against a government that regulates it.
