In 2050, Chinese politicians will talk about India the way Donald Trump talks about China.

Imagine a Chinese version of Donald Trump blathering about his readiness to stomp all over India and make China great again.

Give it a few decades. It may well happen.

America has lost a lot of jobs to China — about 1.5 million manufacturing jobs from 1990 to 2007. And no one wails on this point over and overquite like Donald Trump.

But China won't be China forever. Its manufacturing boom also helped China's mammoth population surge into the global middle class. As China's per capita wealth continues to grow and it shifts into a service economy, the world's manufacturing jobs will start moving to India, Africa, and other parts of Asia.

To see how this might play out, in terms of the overall global forces at play, we can look at data put together by economist Branko Milanovic. Below is a chart on how global incomes changed between 1988 and 2008. Imagine the x-axis is everyone in the world lined up, in order of how rich they were in 1988, from left to right. The y-axis is how much their incomes increased over the time period since.

(Graph from "Global Income Inequality By the Numbers" by Branko Milanovic.)

Now, you see that divot on the right-hand side, between the 75th and 85th percentiles? That batch of poor souls whose real incomes actually wentdown over the last two decades? That's the working class in advanced Western countries. It's Americans who support Trump. It's also Europeans who support the rising anti-immigrant, anti-trade nationalist parties in their own countries. As Matt O'Brien put it at The Washington Post, that chart is something of a Rosetta Stone for understanding the political unrest here in the Western world.

But O'Brien also suggested something more hopeful: that our loss of jobs to China was basically a one-off event.

In the case of America, that may well be true. As countries develop, their populations become richer and are able to provide more demand internally, and that powers the economic shift from relying on manufacturing to relying on services. And since goods are a lot easier to export than services, it's also much easier for manufacturing industries to go running around the globe, chasing the poorest — and thus the cheapest — populations of workers. (Though it's worth wondering how many services may become exportable in the digital era.)

America has already gone through this process. Our manufacturing jumped up and left for China. Over there, the manufacturing-to-services shift is still underway, but is at its turning point. So where do the manufacturing jobs go next?

Here are some more charts that economist and data visualizer extraordinaire Max Roser created, based off data Milanovic put togetherwith Christoph Lanker. The x-axis is level of income, the y-axis is population. Here's 1988:

And here's 2011:

China moved decisively into the global middle class over this time period, but India, Africa, and the rest of Asia are still coming up. As they do, the manufacturing jobs will likely jump from China to them.

Enter Chinese Donald Trump to capitalize on the anger of China's working class.

But there may be a way to avoid it. China has been running a big trade surplus with America, exporting more than it imports. (America, in turn, has been running a trade deficit with China — and everyone else.) But that's actually the reverse of how textbook economics says it should happen. Developing countries are supposed to buy goods and borrow fromrich countries as they build up their own economies.

The thing is, this textbook process requires the developing country to provide demand for its own economy internally. And that requires egalitarian distributions of income, so that everyone in the developing country can consume. But China is super unequal. And to stay unequal, the Chinese government depressed its currency, which allowed it to bleed demand from America, and create its jobs that way instead.

Meanwhile, that loss to our internal demand made it harder for America to generate jobs here. The problem wasn't so much that America lost manufacturing jobs per se, but that nothing else came along to replace the role they filled in our society. And American elites have been basically fine with this situation, since they benefit from inequality here as much as Chinese elites benefit from inequality over there.

And that illustrates the way out: The trade relationship between America-the-rich-country and China-the-developing-country has been deeply unhealthy for both sides. Once China becomes the rich country, maybe it can do better with India and Africa and the rest as they develop.

And that could help us all avoid Chinese Donald Trump.
