Well put Donald and a very important column. Obama's grade school arithmetic makes the math turn out right, but not in the real world. It is more complicated than that. You can't raise taxes by 10% and get 10% more revenue, any more than Wal-Mart could raise prices 10% and get 10% more money. Changes in taxpayer and buyer behavior need to be factored in. Almost anybody ought to be able to understand that. Oversimplification is deception (lying).
