It’s less complicated than that. Externalities are when an individual profits but others pay the price. Think of climate change. And when a small number are so rich they control the government, so there’s nothing to stop them. It’s narrow incentives driving the whole thing.

They love it when the richest people do well. They dont care about how anyone else lives. The poorer other people are better they feel about winning.

Those you call "capitalists" love monopolies as long as they are theirs. They love captured market. They dont care about competition unless it is someone not them competing to provide for them on lower price.

As of now, billionaires dont want or need strong economy as a "middle class and lower class doing good". They want the "our wealth goes up, we are getting tax breaks, if lower class pays for it cool" kind of economy.

The poorer people are that are still able to work, the cheaper labor is. It's really that simple.

The economy won't be bad. The numbers will look good for them. Also they aren't capitalists. Try to keep up.
