Greed isn't even good for business, lol.
Look at the gilded age of America, and how America was destroying itself, saving itself and increasing its economic strength with taxes on the wealthy: it was the 1916 estate tax, 1922 capital gains tax, combined with the rule against perpetuities (which is being eroded), which laid the foundation for economic growth, combined of course, with FDR's new deal, where concentrating economic resources of the state into people, rather than rich assholes (who do not trickle their wealth down) when working class people are the drivers of the economy.
America, the largest economy in the world, is driven by consumer spending, accounting for 60% of GDP. So, if more people have money, better jobs, better education, they'll spend more, creating more wealth.
But rich people are stupid, because they don't understand that concept. Being enabled by people who worship at the altar of wealth, by pretending Elon Musk is Iron Man, just ensures that people, who aren't rich, support the fictions and cult of personality of the wealthy, who are ruining the world. Yay.
