Yes, and it’s simple and effective - Tax them and limit the huge transfers of intergenerational wealth. When the US had a robust taxation system with high marginal rates for the highest income levels, we also had the strongest and most robust middle class. It powered the “American Dream.” Having individuals hoard billions of dollars and build familial dynasties isn’t good for society as a whole.
In my opinion, it all begins with ending the system of legalized political bribery, getting dark money out of politics, and making politicians accountable to citizens again.
