Governments to stay in power with Fiat Currencies, abuse them. Supposedly during good times, no deficits at all. The currency can shorten recessions with priming. Wars that are costly actually need fiat currencies for resources. We kept some level of control until President Johnson's Great society, Viet Nam War, and Moon Program plus other expenditures. In a matter of a half-decade or so, we were getting of the last string to gold that was agreed to with Bretton Woods in 1944 as we became Top Dog. So, nations used our currency as the go between, or it was a safe investment in the dollar. However, they had the option to take their investments in gold. And we did not have it. Charles DE Gaulle of France set it off from that request. So, Nixon had to take us off of that as our deficits started to grow. We ended up tying in our dollar with oil. Saudi oil. All of the social programs took a meteoric rise. Politicians told us one thing on the growth of them, and we ended up with another. Look at the arguments on anything that is a social program and cuts today. One day there will be forced cuts. And it will be painful.
