Sorry, but I don't think you know what you are talking about. I actually come from an ex eastern block country (and was born under communism) and I can tell you that nobody prefers soviet style appartments to what's available today.
Centralization of power into the capitals of nation-states brought us the meat grinder of WW1 and then the horror show of WW2. The centralization of power in Washington, Moscow and Beijing brought us to the brink of global nuclear war. WW2 was already hard to escape but no place on this planet will be safe when the Ukraine thing goes sideways.
Yeah exactly. We "need" global communism to fight Climate change, right? I'll pass. If there is a solution it's going to be a bottom up technological innovation.
There was no time and place except under mostly decentralized capitalism when workers where not exploited. Whatever that word even means to you. Normal socialists seem think every transaction is "exploitation".
It's pretty black and white. Centralization only allows for one solution and smothers all others. If the central plan fails, like central banking does right now, it fails for everyone all at once and there is no escape.
It's literally creating money out of thin air. The process is just obfuscated behind shell games and big words.
Anytime someone borrows money from a bank new money is created. It's supposedly not a problem because when the debt is paid back the money is destroyed again. In reality, though, debt is never paid back, especially by governments. Instead it's refinanced be taking on ever more debt. The amount of debt is only ever growing and so is the money supply.
Central banking is the central planning of the availability and price of credit.
Central planning of food production has created famines with no equal in history.
Central planning of housing created those lovely soviet style "housing" block developments while the beautiful inner cities of eastern europe rotted away.
Central planning of car production gave you cars like the Trabant which you literally had to queue 18 years for.
I am sure there is nothing that could go wrong with central planning the money supply but just in case economic live feels harder than it ought to maybe it's because of certain institutions continuously inflating away the value of your currency.
