Isn't it curious how when America faced a real financial crisis that the very people who authored "trickle down economics" actually enacted a diametrically opposite approach? Instead of thinking that lavishing more riches on the already rich would somehow "trickle down" to the masses, when it really mattered, they created a "stimulus package" that put money into the hands of the American people knowing that it would, in fact, "trickle up".
It's funny how a true crisis betrayed conservatives' real understanding of economic policy. Of course, operating government almost exclusively in their personal interest has been the typically modus operandi of the conservative elite. Financial deregulation and the general "laissez faire" approach to business that engorged the rich but in so doing almost destroyed the American economy is a direct by-product of their approach. When that almost bankrupted our nation, however, they were forced to reject their traditional self-serving pandering and do what they knew would have a real effect.
Going forward, instead of the Supply Side measures for the wealthy that they cherish, this current episode, hopefully, taught them an important lesson. Economic policy with a more populist objective is both the most economically sound, and the correct, thing to do. It helps both the masses of the American people and the economy in far more fundamental ways than just focusing on the very few at the top - and then theorizing that the rest of America will somehow benefit from their "droppings". Even if your interest is only with the very rich, as the recent Bush stimulus program demonstrates, populist economic measures create the economic groundswell that ultimately, of course, 'trickles up' through the economy to business owners and shareholders.
The Bush stimulus package tells the story in a bold and clear way: trickle down economics is a sham (btw, beware of the "Fair Tax" - TDE's philosophical offspring). The fact that the administration is considering yet another round of stimulus checks underscores this point. Let's finally put the trickle down approach to rest and adopt a more honest and populist approach to both economics and politics in the future.
