Economics is mostly how humans rationalize who gets what and why. It's how we instantiate our preferences about status, privileges, and power.
The most powerful forces in economics are not numbers or facts. They are prejudices and preferences. No amount of evidence will ever change the degree to which many of the rich and powerful prefer themselves to be richer and more powerful and others poorer and weaker.

I have, oddly, two ski houses - trying to sell one.
No matter how wealthy a few plutocrats get, we can never drive a great national economy. Only a thriving middle class can do that.
The thing about a real economy is that it actually is like the game of Monopoly in the sense that when one person has all the money, the game is over. And in a game of Monopoly, of course, that's quite charming, but in a real economy, it's much more problematic.
