Time for a new metaphor??

Now that Obama's in (was there ever any doubt?) there are a few commentators - the conservative types - who are saying stuff like - "Well, he can't keep his promises on taxes, especially to the richer types - that would be disastrous!" One of those commentators is Michael Campbell - big time financial guru here in BC - who can't even pronounce Obama's name correctly. Imagine: O-BAM-AH. If Canadians keep this pronunciation up, I will retaliate with CAH-NAY-DAH!
Anywhoo... I was thinking about Obama stating that we need to get rid of this old ecomomic model of "trickle down" theory. This, I believe, was started by Reagan (who Obama has thoroughly studied and I believe admires in some ways -- wait : a president who STUDIES something, as in, READING???? What a difference!!) This 'trickle down' theory is a tired metaphor. If you try to hold water, some of it always trickles down. The problem is, there is no trickling....the economy has nothing.
A better metaphor may be of a glutton. The glutton is at the table, slamming down all the food he can get his hands on. As he eats quickly, food flies off the table: We are just getting the crumbs. This displays the need for a different system: We need to take some of that food off of the table and actually give it to the poor souls on the floor. The trouble with 'trickle down' is that it doesn't take into account human greed and the creativity of the human to discover ways (loopholes) for keeping the most food on the table.
This is what we've had and the system is collapsing due to human greed. The gluttons at the top are crying over the loss of food. That's all there is to it.
