When it's finally explained how service economy can be sustainable long-term, I suspect many people would have no problem with outsourcing production whatsoever.
Maybe we'll see a rise in business creation when people can't get a job working for someone else. It happens during every recession. I wonder what the impact would be of corporate jobs becoming increasingly rare.
(Of course, the USA still produces lots of stuff you can kick. Don't worry.)
Also, where the confidence that Chinese would continue to need American investment advice comes from? If they get the majority of capital and trade along with industrial base, wouldn't these jobs simply follow the money? Americans certainly didn't need any external help back in the day.
America did use lots of foreign help back in the day. The British helped finance the railways. But America did not rely on foreign finance forever. After the First World War there were the greatest creditor nation.
The rise of America has not dented the European standard of living. And neither should the rise of China curb the American living standards. Relative decline is not absolute decline.
