As concise as possible:
For the last 45 years, the Federal Reserve has lowered interest rates from 20% down to basically zero.
Because rates were low, the USA slowly stopped producing and instead borrowed money in order to do lots of stuff, including investing in tech, but mostly consumption. The USA consumed, and it financed it with debt.
The whole world uses the dollar, as agreed in the post-ww2 Bretton Woods system.
Because of that, the world not only finances the USA by buying the debt (lending the money) but also finances the USA by just holding dollars, because as the USA prints those dollars, all these countries lose purchasing power which is transfered to the USA.
What's happening right now AND IS BEING IGNORED, is that INTEREST RATES ARE GOING UP.
People are too focused on the Federal Reserve and on the spending, which historically have been the only two things you need to look at. They are not noticing the interest rates going up.
What's about to happen: Interest rates are going to get attention when they go through 5% or so, and we are going to get a liqudity crisis. There is a lot of evidence that we already have a liquidity problem all over the place, but the market, companies etc are ignoring it for now based on the idea that we will get globally looser financial conditions.
Instead we will get higher interest rates, and when the Fed steps in to do QE, it will have to buy a lot more bonds and a lot more stuff than people realize right now. That means huge inflation, but that inflation, unlike before, will come with higher interest rates because the world in reality will not be able to finance the USA at this level, it will be impossible.
As a result, the second part of the USA's gravy train, the one where foreign companies, people and central banks hold dollars, goes away.
The dollars that currently exist are heading back to the USA, and the dollars that are about to be created will not be held like before. Inflation + depression.
