Yep. What some believe "unbacked currency" means is a currency not backed by precious metals, but what economists mean is a currency unfixed to the economy's output. If the GDP increases by 4%, a 4% increase in currency will not cause inflation and indeed basically cannot cause inflation.
As of 1980 when I was studying economics in college ... uhh, grade school ... the mystery was how the US economy was in a recession yet inflation was exploding, something called "stagflation." Friedman had warned decades earlier that printing money to try and fuel growth was going to cause inflation. Jimmy printed money to try and trigger growth to start economic growth and of course his theory failed and of course printing money in a recession caused inflation.
I became a Republican for life in college. I saw my prospects under Jimmy Carter, compared to Ronald Reagan. The choice was pretty damn clear - and still is. Trump vs. Biden? Who the **** would choose Biden??
