Ok, so trickle down economics work in your opinion?
Are all the hundreds economists that did research and proved it doesn't work also marxists?

It's actually true that the rich keep getting richer. It has been like that for many decades. And neoliberalism is to blame to a large extent. The idea was that if we favored economies of scale, while the efficiency would benefit the rich most, much of it would "trickle down" to workers. This what Thatcher and Reagan promoted to the world.

Ever since things have only been getting worse though.
