Relatives of mine owned a small factory. They bought it just as Bush tax cuts were going into effect. It failed in 2006. China was able to undercut their costs to the extent that demand driend up for what they did in the US. Many other similar factories folded between 2000 and 2010.
Chinese factories were able to give their customers quotes that, in some cases, did not even cover the cost of materials, let alone labor. Apparently they had some sort of government subsidy that made it possible for them to do this.
The idea that a broad based reduction in taxes for the highest earners, no matter how many employees or what the business, will created jobs is simply bogus. Call your representatives and tell them so.
