alt Hacker NewsThe US has the second largest manufacturing base in the world after China. It's larger than India and is even slightly larger than the EU. It used to be the largest. Moreover, if the premise is that you're trying to bring back manufacturing capacity, it doesn't matter if something is currently made in the US, what matters is what it would cost if it was, because a tariff in excess of the difference would then make that cost effective.
Obviously in the latter case you would then have to wait until that manufacturing capacity comes back online, but "customers switch to a domestic product" isn't the only thing that can cause foreign manufacturers to have to lower prices. They could also switch to substitute products or reduce consumption and then foreign manufacturers would still have to lower prices to limit the extent to which that happens.

China has a third of global manufacturing capacity (and have to run flat out to avoid deflation due to domestic consumption that will never grow to meet domestic production capacity). Only the unsophisticated could believe the US is going to increase domestic manufacturing capacity at the levels needed to make domestic sourcing superior in some manner. That’s why these tariffs are not grounded in reality.
In three years at the most, these tariffs are done. Cheaper to eat the premium in the short term versus suboptimally invest capital in long duration investments (ie local factories and equipment to fill them). Manufacturing jobs continue to decline, as they have since the election.

While in the abstract and academic sense this is true, in practice there are two big problems that make it an utter non-starter*:
1) Due to the absolutely massive supply chains that have been built up in East Asia (not just China, but many other countries around there), and lack of same in the US, even for products where it's physically possible to produce it all domestically, from the raw materials on up, it would take decades of sustained investment without return before actual consumer products could be made on anything other than a one-off basis. Any step that can't be done in-country gets the tariffs slapped on again. And there are a fair number of raw materials we just don't have, at least not in the kinds of amounts that, um, the entire rest of the world does, that are required for mass production.
2) Trump isn't applying tariffs in a strategic manner to get domestic manufacturing to come back. He's applying tariffs as his personal punishment stick, and to all appearances that's the best he's actually capable of doing with them. In order for any of what I described in #1 to happen, ever, the tariffs need to be applied consistently, predictably, and for a long time.
Trump doesn't want to do any of that. He's just found a magic stick that makes people kowtow to him, and he's going to use it however he pleases.
* Not that I think you're unaware of these, based on your post; to a large extent I'm just expanding upon your second paragraph here.

Of only end products. The "largest manufacturing base" is misleading when majority of inputs for your finished goods are dependent on imports.
> it doesn't matter if something is currently made in the US
It definitely does matter. The right way to have gone about this was to first build the manufacturing capacity in US before imposition of tariffs. It was done in the reverse, which led to US revealing its hand too early, allowing for rest of the World to re-calibrate and start the process of de-dollarization.
> foreign manufacturers to have to lower prices. They could also switch to substitute products or reduce consumption and then foreign manufacturers would still have to lower prices to limit the extent to which that happens.
It won't happen. There is no reason for exporters to lower prices when tariffs only set a new normal. Once the prices have gone up and consumer spending has stabilized around those jacked up prices, that will set the benchmark. Just study history. No product has been devalued due to any contingent circumstances unless the product itself becomes obsolete. Here you are not talking about novel products being developed and manufactured that will obsolete something popular. You are talking about bringing back manufacturing of nuts, bolts etc. Things that are critical and have an already established price in the market that will only go up higher in price once manufacturing moves to US eventually. Rest of the World will adjust to the new higher price.
