Germany, 1948. The Reichsmark is worthless. Cigarettes function as currency. Factory output sits at half its 1936 level, and the Allied occupation runs a price-control regime so absurd that farmers feed grain to livestock rather than sell it at the dictated price. Then Ludwig Erhard walks into a radio studio on June 20 and tells the German people the controls are gone. He did not ask the occupation authorities first. He told General Lucius Clay afterward that he hadn't altered the regulations, he had abolished them.
What followed embarrassed every Keynesian planner watching from Washington and London.
The Deutsche Mark replaced the Reichsmark at brutal terms: roughly 100 old marks for 6.5 new ones. Hard money, scarce by design. The black markets emptied overnight because goods reappeared in shop windows the moment prices could speak. Industrial production jumped over 50 percent in the second half of 1948 alone. And here is the part the textbooks bury: through the 1950s, as the economy grew at better than 8 percent a year, the cost of living stayed remarkably flat. Germans got richer while prices held or fell. Productivity outran the money supply, which is exactly what's supposed to happen when a central bank keeps its greedy paws to itself.
Falling prices alongside roaring growth, rising real wages, and a currency people actually wanted to hold rewarded Erhard's Germany. Deflation is not the disease. It is the natural reward for producing more than you did last year.
The Bundesbank inherited this discipline and guarded the Mark with a stinginess that drove politicians to fury for forty years. That stinginess built the strongest economy in Europe. Then the same political class buried the Mark under the euro in 2002 and handed monetary policy to people who consider 2 percent annual theft a "target."
Erhard proved sound money and free prices rebuild a bombed nation in a decade. Every finance minister since has worked very hard to forget it.
@guillermocarone@ai0dev Well ofcourse i would go with less external units, you can install those on the groundfloor allso or basements, its an non issue if you really want to implement AC
