So, during the Great Depression who ended up doing well? What can be applied to today?
The US is going to debase itself endlessly through spend-print-spend-print. At some point they may load up enough debt that the economy suffers a gradual heat death, in the style of Japan, wherein too much of your national capital is going to debt maintenance, sitting in a low yield blackhole sucking the dynamism out of your system (instead of going to productive use, business expansion, R&D, et al).
There's absolutely nothing particularly interesting or special about the direction the US is going. It's very, very, very easy to see what's coming and has been for ~20 years (since Bush nearly doubled the size of the Federal Government and blew up our finances with simultaneous tax cuts + massive spending expansion, we've never turned back from the bleed).
Gold has gone up ~10x since the early Bush years precisely because of the USD debasement, that's the reduction in value in the dollar being represented in the ultimate store of value. All of it has been remarkably predictable. I've been chirping about it forever here and there's nothing special about my insight either, this stuff is plain as day national econ 101.
We were 10 years from paying off the national debt when Clinton left office. 10 years!
I say this as someone who thinks Bush was an absolute idiot and would love to see the government shrunk.
TSA is basically a jobs program, what happens if we get rid of it?
To be fair, if the US government had continued paying off the debt, the only way the (global) books would've balanced would've been for the US populace and businesses to take on waaaaayyyyyy more debt. Not sure if that would've been better.
