“Is all our plumbing, roads, bridges, etc. going to disappear?”
This guy might be the kind of nut who also predicted the rapture in 1988. That said, it wouldn’t take very long, with no money or desire to maintain them, for our infrastructure to fall to third world levels.
Most of our modern infrastructure was built after WWII - and with bridges the safe lifespan is some 50 years give or take... Add 50 to an average of 1955 and you’ll see we’re long overdue on bridge replacement. Our other infrastructure’s the same. Without the money to maintain it, it’ll go quickly.
Driving across the southwest rural areas a few weeks ago, I was amazed at how many abandoned buildings there already are. Nasty looking structures with walls knocked out, etc.. Apparently that is natural for the desert southwest. Boom and bust cycles. Heck, back in the 80-90's parts of Detroit City looked like a war had taken place there. Our infrastructure is already falling apart due to neglect and lack of maintenance caused by deficit spending (too much money servicing the debt).
