It's cheaper.
Your experience is with manufacturing is unfortunate but show me some data. The American economy generates
a higher nominal GDP than the Chinese economy.
The Chinese economy has the largest secondary sector (manufacturing, construction) in the world by industrial output. The American economy has the largest tertiary sector (services) in the world.
According to the
Census Bureau, the U.S population is at least 326 million people.
China's population: about 1.4 billion.
The American GDP per capita is 57,000 USD.
The Chinese GDP per capita is 15,000 USD.
We get a larger bang for our buck out of our people per 1000. We invest more in our people via the service sector, the more productive economic sector, because the returns of the service sector are fantastic compared to manufacturing. Even China is trying to shift to a more tertiary economy.
The service sector is more productive than manufacturing.
I've provided data from the IMF, CIA World Factbook, and U.S Census Bureau to make my case. I'm holding you to the same standard as myself, step your game up.
I didn't say that there was a damn thing wrong with manual labor.
As for coal-mining, I'm fine with those ghastly jobs being shipped overseas until we can completely automate them or replace them with jobs that favor renewable energy. As for now, we can afford the tariffs. If we want China to give us a more favorable deal with the coal, we need to get better ambassadors.
