As usual, Uber Dave spews falsities. First off, there is no such thing as "liberal economics." That is his way to meaningless brand something that is nothing but propaganda. Economics is, well, economics...it is not 'liberal' nor conservative. The issue is, in fact, the basic 'supply' vs. 'demand' policy approach. From Reagan on, all data indicate that 'supply side' economics is wrong and does not work, despite right wing think tank attempts to the contrary. As STANDARD (as opposed to 'liberal') economics says, economies occasionally need stimulation (demand). This is what happened after WWII so successfully. All 'supply side' economic policy has done has created income inequality and reduced wages for the middle class.
