Macroeconomics is whats up with the prices.
It is a three headed dragon, and we see two of them already.
* Massive increase in money supply (more money chasing goods) - CHECK. We printed and our sins do not go away as quickly as we wish they would.
* Supply issues resulting in fewer goods to buy (same or more money chasing fewer goods) - CHECK.
* Wage-Price spiral wherein employees demand higher wages to account for their costs, which increase the cost to the employer, which has to increase prices, which leads to employees demanding higher wages. - POTENTIALLY NOT HERE YET.
Wage-Price spirals are the things of nightmares and when it happens, the only way its ever been broken is via war or a prolonged recession.
Hold onto your hats if that happens.
