>It turns out production of most goods is commoditized and a race to the bottom (assuming free trade), so if you want margins that can support high salaries, you have to move up the value chain (read: services).

I know, right? When you go home and sit down on your Oracle database to relax, then go to the kitchen to cook your evening meal in an AWS Lambda, then afterwards relax a little more by changing into some spreadsheets, it really puts it into perspective: everything a person needs is technology and software, and who wouldn't want to dominate that industrial sector?

>If we keep tariffs high enough for long enough, we will bring back manufacturing jobs.

Sure, but we don't have a commitment from Trump's eventual successors that they will continue, let alone from the opposition party. In other words, everyone knows that it will not continue long enough... the only real question is how do they best mitigate the pain while it does continue short-term? Trump could easily drop dead of a stroke or heart attack tomorrow, he is not a young man or in great health. But even should he survive the full term, the clock's already ticking. Why would anyone commit to an expensive long term investment today, when January of 2029 it will no longer be necessary?

>They will not be high paying unless unions artificially constrain labor supply.

The labor supply is already constrained... demographic implosion is well underway. The only way to unconstrain it would be to import millions of people from foreign countries.

>If we want to withdraw from the world economy we mostly can,

Why would this be withdrawing? Who do you think we'd want to sell the products to anyway? No, I believe we're talking about switching our role from consumer in the global economy to producer. What do you think the Chinese could even buy with all the trade deficit cash they're squirreling away, when we don't make anything? Some large chunk of it is buying up stock, real estate, etc. Give them something else to buy.

>but don’t expect to have as nice of a life afterward.

I'm like a 8th class (or lower still) software engineer in a fly-over city, and even my salary's six figure. The rest of you I always figured were doing better still. So I can understand why you don't get that for most people in the United States, "nice of a life" hasn't been a thing for generations, it's mostly stories they tell each other that have been repeated since the 1960s that originated with their great-grandparents. I mean, I would've thought some of that leaked through reddit and other such forums, where they complain about working 3 Uber-Eats-style jobs and never having a day off, only to be able to scrape by in some shit apartment while wondering how to keep their crappy used car from being repossessed.

You swim in this little bubble of atypicality, never noticing that the cheap clothes on the Walmart shelf show up from the distribution center looking what we would've called threadbare just 30 years ago. That no one you know (even those earning like you do) owns real furniture even if they earn a salary like yours. Even the "fancy" McMansions that you see from time to time are garbage, constructed as if no one cares that they last longer than 20 years. How many of the consumer goods in your home can you lay hands on that aren't 50% plastic or more?

Nice of a life. Haha.
