It is astounding how many people naively just think "Too much money = bad". Billionaires don't really have cash sitting in their houses. They created companies, often from scratch, that wouldn't otherwise exist.

GDP per capita grew because the wealth was created, not stolen. The entire pie got larger. We lifted people out of poverty from 90% in 19th century to what it is today 10% through capitalism and trade.
We need more billionaires to create wealth and propel society forward.
Crony billionaires, politicians, inheritance wealth, etc. need to be condemned and we usually throw the baby with the bath water along with the whole tub.
Billionaire hate is getting out of control because people are convinced naively. I suspect some malaise in economics education.
