Because while China hails globalization, it imposes a 25 percent tariff on imported cars (while America imposes only 2.5 percent) and 50-50 joint ventures and technology transfers for big companies that want to gain access to China’s giant market. But China gets away with it.

In technology, China has embarked on a plan called “Made in China 2025” that’s plowing government funds and research into commercializing 10 strategic industries while creating regulations and swiping intellectual property from abroad to make them all grow faster. These industries include electric vehicles, new materials, artificial intelligence, integrated circuits, biopharmacy, quantum computing, 5G mobile communications, and robotics.

And Trump? On the change in the climate, he’s promoting coal over clean energy, like wind and solar, and has appointed climate-change deniers to all of his key environmental posts. While China is run by engineers, Trump doesn’t even have a science adviser. He’s refused to fill the White House Office of Science and Technology, which, as Newsweek reported, “has been without a boss for the longest stretch since its establishment in 1976.”

On globalization, Trump tore up the Trans-Pacific Partnership (TPP) deal, which would have put him at the helm of a 12-nation Pacific trading bloc (without China), built on U.S. interests and values, and would have eliminated as many as 18,000 tariffs on U.S. exports to countries that, together with the U.S., control 40 percent of global G.D.P. And then he went to China and praised Beijing for beating us at our own game! Well, Donald, when you unilaterally disarm, that tends to happen.

By the way, the 11 other TPP nations are now trying to create their own free-trade zone — without the U.S. So after decades of America trying to push all their markets open, they’re going to open without us. Nice going, Mr. President, China thanks you, because these countries will be much more vulnerable to Chinese economic pressure with our presence diminished.

On the change of the climate of technology, Trump is pushing a tax bill that is based on no analysis of emerging technologies and how we might reform our tax laws to incentivize more investment in them. Actually, the bill would eliminate the $7,500 tax credit for electric cars; shrink the tax credits vital for enabling wind projects; and impose a tax on the endowments of our wealthiest colleges — i.e., our science and engineering treasures — endowments that colleges use to fund research and extend scholarships for the neediest students.

“This will be wounding to one of America’s gems,” its institutions of higher education, Drew Faust, the president of Harvard, said to me. And it’s basically being done to cut taxes for the wealthy.
