Money does trickle down but what it trickles down onto is a determining factor in economic growth.

When rich people put their money into employing people for non-productive servant type jobs, welfare for people (to not work), loans for people to go to college (to not work, at least in the short term), hand outs for their children and family members (to not work) then the end result is a lot of people not working and a lot fewer things being produced by the people who do work.

If a rich person buys a yacht or a private plane or a hundred million dollar mansion, that creates economic activity (people have to build that stuff) but it does not have the same secondary economic impact as investing that money into a factory, basic infrastructure, R&D, or some other productive use.

Money is trickling down, but far too much of it seems to be trickling down to a non-productive servant class and non-productive veblen goods.

Sarcastic, or do you have some reason to believe that'll actually happen this time?

It will NOT happen. It has never happened that way, and there is nothing especially unique or different about the economy today that would make it happen.

I could say if this tax cut doesn't help we'll just do another and then paradise for all starts. But that would be too sarcastic.

Comrade maxxx is secretly hoping you don't want to be patient.

I think I need to clarify that I was sarcastic. Nothing will trickle down.
