The economy for the trans national corporations couldn't be better. For wage earners, not so hot. Why?

Right after WW2 when labor unions were strong, American corporations made the best stuff in the world AND made huge profits. Taxes were high, but everyday our social and physical infrastructure got better. We built heavy equipment, trucks, cars, washing machines, refrigerators, houses and tall buildings. China built re-education camps. Now the unions are busted, taxes are rock bottom and we don't make anything. We trade our industrial base for 'Everyday Low Prices' that aren't even that low and the Made in China 'stuff' is pure crappola! The GOP/Tea/Fox/Jesus freak party doesn't seem to have a problem with this and they for sure don't want Barack to do anything about it either. Is this the end of the Republic? A massive bloated military that can't defeat two 3rd world countries based on a worn out industrial base and populated by poor people just doesn't seem like the way to go. Evidently there are lots of people who don't really care, or simply don't understand the situation.
