I'm American. I grew up in the rural Midwest. The truth is that much of this country is a depressing shell of its former self. The town I grew up in is all but dead -- about 12,000 people still live there, though. The nearest big city, previously a hub of manufacturing innovation, has been on a steady decline for decades. Since the 70s, more and more powerful drugs have been flooding into the broad geographic region, decimating entire communities and creating generational cycles of poverty and addiction. It's an absolutely brutal combination that has totally killed almost all innovation and output in huge swathes of this country. Candidly, even if you brought back manufacturing to the area, the local population is so dependent on drugs that you'd struggle to even find workers today.
Today's drugs are so powerful that addicts would rather live in total poverty with drugs daily than have a high-paying job without drugs. Every small business owner in these regions knows this, but the true scope and severity of the problem can otherwise be hard to fully notice and appreciate. It's not possible to operate a small business in these regions without encountering the drug problem on a regular basis.
Do I think tariffs are going to fix this? Honestly, probably not, for the simple reason that Trump is old and won't be here much longer even if he tries to install himself as a dictator. The winning strategy for much of the world is to likely wait this out to some degree -- best case scenario for others is that this will just get reversed or significantly mitigated in 3.5 years, which is the blink of an eye on global timescales.
Nonetheless, my heart goes out to the incredible loss this country has experienced over the last few decades. It's truly heartbreaking and devastating that we've sold out so much of the country for short-term profits to such a degree that we can probably never break out of the cycle without severe pain and sacrifice.
