We chose to outsource a large percentage of manufacturing jobs to China in favor of getting "cheap labor" to maximize profits for corporations. From the corporation's point of view why build something in the U.S. and pay an employee $15-$25 per hour when you can get the same product made in China for $1-$2 per hour and not have to concern yourself with providing employee benefits or dealing with air and water environment regulations.
Unfortunately bad trade deals and less manufacturing jobs eliminated lots of well paid blue collar jobs in the U.S.
When the majority of people are earning less money they tend to spend less money which is the engine of any country's economy.
Former high paid manufacturing blue collar workers now find themselves in low paying service jobs. Some of these jobs were historically meant to be "stepping stone" jobs one worked while they were going to college or these jobs were seen as a way to bring in some "extra money" to pay some bills or buy something special. These jobs included working fast food, grocery store bagger, cutting lawns, delivering newspapers and so on. They were usually held by our youth.
Today it's not uncommon to see these jobs being held by people in their 30s, 40s, 50s, and beyond. I haven't seen an actual "paperboy" in two decades! Grown men with vans now deliver newspapers. Middle aged fast food workers are looking to unionize in order to earn $15 an hour for flipping burgers. Most people who pay to have their lawns mowed today deal with "professional landscaping" business owners. The days of the little boy in the neighborhood knocking on doors to offer cutting grass and shoveling snow services are gone! Naturally this hurts teens and young people. The "stepping stone" jobs are now careers!
Even high-tech companies have outsourced their tech support jobs to countries like India in order to maximize profits.
Essentially our global economy focus has shrank the middle class living standards in the U.S. Eventually this will happen to China when they get to a point where it will be cheaper for their companies to make products in some third world country. However they have a long way to go to reach that point.
Then again it may never happen as a Communist government tends to control it's people and corporations.
Nevertheless I can't imagine many people wanting to move from the U.S. to live in China. I'd rather stay here and say things like; "Would you like a hot apple pie to go with that?" :-)
