Restoring the middle class

One start to restoring the middle class in America is having Congess stop free trade with China and begin to impose import taxes on foreign goods so that American products are on a fair playing ground in competition with foreign goods.  This will restore manufacturing in America.  Congress must also give tax credits to companies who keep their factories in the USA and employ American workers.  Those companies who outsource their work and factories should have a tax burden.  These US factories must allow their workers to unionize, so that they are ensured a living wage.
