That would be "taxes go down economic activity goes up". Which is the thing that's taxed
It's pretty hard to argue against that.
Cutting taxes for the wealthy is always touted as an economic stimulus ala Adam Smith's "Invisible Hand"... but history shows us it never succeeds.
Wealthy no, business's yes.
The problem is Liberals, like yourself, have absolutely no way to distinguish between those two groups. In your crusade to punish those evil wealth-hording scourges, you end up also punishing all the people who are forming or running business's that hire people and drive the economy. You end up shooting off your own arm in your attempts at social justice.
Face it, evil wealthy Bond villains are smarter then you, much smarter. They are so smart that they've long since discovered how to mobilize an army of minions to do their bidding and fight against their competition at wealth hording, your part of that army. Any attempts at bleeding or hurting those evil wealth-hording Bond villains will do absolutely nothing but further impoverish yourselves and further the goals of those same evil villains you pursue with fanatical fervor.
Funny thing, President Trump was once part of that cabal of evil wealthy overlords, he fully supported the Democrat party whenever it was politically advantageous, and then supported the Republicans when it fit the moment, all like the opportunist he is.
