The Chinese government has manipulated their currency so that their exports were 40% cheaper than they should have been if it were really a free market. That is like an invisible 40% tax on American manufacturers.
Of course weakened manufacturers has meant less political power for manufacturers and thus weakened power for job creators. Hence the insane regulations, Obamacare and all the other burdens on producers.
China will crack within the next two to three years and lose the ability to manipulate exchange rates as inflation hits. When that 40% burden comes to an end, manufacturing will return to America. Power will return to the producers. Regulations will be cut. Prosperity and jobs will return to America.
The Chinese haven't done anything the Japanese have done for 40 years.
Sure, there is plenty of blame to go around for the collapse of American industry, but the Japanese were only too happy to scoop up the business behind a closed market.
