I need a good rebuttal for a right wing tax metaphor

20. The whole analogy is based on the rich guy being the guy who really runs the show...

...the whole "engine of the economy" thing.

The financial guys aren't they engine, they're the lube system. When functioning properly, they are the oil and grease that lets all the parts move freely to do what they are supposed to without excessive wear and tear. A really good system also regularly clears away old oil and grease so that it doesn't gunk up, but still, it's not the engine.

What we have is a dysfunctional system that thinks it is successful if collects as much oil and grease as possible in one spot; that's what its incentives are. And to do that, it strips as much as it can from every other place, and is ever more stingy at parceling out any. So all the parts wear more and break down faster.

And the lube system that thinks it's an engine does nothing but complain about how run down the other parts are and they need to work harder if they want any oil & grease.
