And prior to Obama it is directly related to the millions of manufacturing jobs taken off shore.

The hundreds of thousands of companies that no longer exist as a result.

Add to the above the unfair advantage other countries have over US goods....they pay no tax or fee to ravish the American market while not allowing American products into their country or there is a major tarriff.

The USA has literally given away American manufacturing capacity for the sake of corporate profits and political BS with countries like China, Japan and too many others.

There is no mystery where the middle class went....t=their employment went off shore. It has been going on for years.

There is no politician capable of fixing it until the priority of the people is raised above corporations and foreign BS politics.
