Tax cuts supposedly stimulate the economy, presumably because people have more money to spend. Whether that will translate into 400,000 new jobs is questionable. In order for that to happen, I believe we would also have to export more items that we manufacture. I'm pretty sure we don't manufacture nearly as much as we would like and with countries like China propping up their country in order to keep salaries low, we aren't operating on a level playing field. Without that, we aren't much better off than we are now.
