I appreciate your desire to understand why. Personally, I find that attempting to reduce an extremely nuanced and complex topic into an 8 second sound bite sentence isn’t capable or realistic.
certainly the long duration of low inflation then the world shattering pandemic created inflationary pressures across the board. Wage increase, pent-up demand, supply chain issues, shipping uncertainty (esp Red Sea), wars, shareholder expectations, political turmoil, climate impacts, immigration - all contribute. Some more than others but to really understand - all need to be considered.
