Retail stores don’t work that way. There’s no Scrooge lurking in a dark office plotting to raise prices on the very thing you want. Mostly, it’s a spreadsheet guy trying to balance the price of widgets vs the demand for widgets vs supply costs.
Prices do rise slowly in a healthy economy, and when you get to be my age you can remember when widgets were five for a dollar. This is a good thing. If prices fell, everybody would hoard their money, because its value is growing. If people don’t spend the economy goes to hell. This actually happened in Japan - it’s not just theory.
Republicans have always warned that giving money to the poor would spark runaway inflation and moral turpitude, except when a Republican is president. It’s not as big a problem as they think, and it’s a problem the Federal Reserve can handle.
