Lefties have only one basic problem.  They fail to realize that for every cause there is an effect.  Some examples are adding Ethanol to gasoline was supposed to cut pollution.  Instead the massive diversion of corn for the production has caused massive price increases in the price of corn.  This has resulted in major suffering by the peasants of the world who rely on corn for their daily food.  Cash for Clunkers was a similar program, people got money for trading their old cars in, so that they would buy new cars.  Only problem, demand for cars is not elastic.  If you buy one today, you will not buy one tomorrow.  So low and behold, after Cash for Clunkers ended, new car sales fell.
