If that were the case, the US would be dumping trillions into spinning up manufacturing like China did.
The US has the power to do this, they did it during WWII, and like it or not, this current era requires heavy strategic investments that may not produce returns for decades, if at all. It's what China is doing and if the US were trying to compete, they'd do the same. We were getting somewhat close to this with the CHIPS Act, but that's on the chopping block[1], too.
Truth is US capital is happy to sell off manufacturing capability to cash in on cheap labor, and there is no monetary incentive to re-shore manufacturing capacity unless the government provides serious incentives or does it themselves.

Bringing manufacturing back is a stated goal of this administration.
Nevermind that you're not going to convince an American to work for Chinese wages in a sweatshop. Ignore that.
But the intended outcome of everything Dump is doing is to de-emphasize advanced education, bring back all basic manufacturing, and restore the "traditional" American values (white, straight, Christian). It's an absolutely stupid idea, but he's been pretty clear about it.
I'm no expert, but even if they somehow managed to get manufacturing back, slashing your competitive advantages and just taking the market position of "China 2: This time it's more expensive" doesn't strike me as a winner for exports.
Now they're going back 70 years instead of moving forward. Big brains there.
i.e. perhaps the whole point is that breaking these things will do damage and lower the status and functionality of the United States, making it actively worse by a considerable amount and sabotaging key structural parts normal people wouldn't even know were there.
In short, it's possible that it being bad is the point.
