The "trickle-down" theory of economics imagines capitalists at the top of a Downfall set, with all the counters (capital, ie money). As capitalists invest, the counters tumble through the economy, supplying workers with wages, and goods and services to buy with them. So the more money gets converted to capital, the more there is to "trickle down".

But after more than 4 decades of "trickle-down" policy, it's pretty clear that economies don't work like that. Exactly the opposite.
