Trickle down is all there is, except for command economics.
And command economics is to economics what a jack hammer is to a road.
You can modify the trickle with government fiscal policy and tax policy, but at the end of the day money flows from one point to another.
The modifications seldom really work well, no matter how well intentioned or just.
Command economics is in a sense the destruciton of economics, like in North Korea or the USSR. It really hurts the little guy.
