A decent cartoon to illustrate the difference between trickle down and trickle up.
Republicans tend to favor trickle down. Give producers of wealth tax breaks and subsidies and they will invest in business and jobs and the wealth will redistribute down. All boats rise with the tide but the wealth that trickles to the bottom is very little.
Democrats tend to favor trickle up. Give the poor redistributive wealth because they need it. Problem is they need it to purchase necessities from the wealthy and the wealth is redistributed from the middle class.
Obama seemed to understand the problem with trickle up and for a short time talked about trickle out. Give tax cuts and subsidies to the middle-class who0 are, after all, the true producers of wealth. But he was a lame duck and no one bought his argument.
All this trickling is just Keynesian economics and bound to fail anyhow. The government has no clue what it's doing.
