While that's true broadly, that's handwaving away the specifics of actual pricing strategies by individual companies. The ultimate price of goods is what the market will bear. If the market will no longer bear the inflated prices set by X company, because the free money is running out at the strata of your average shopper at X company, the prices will come down.
Ultimately, consumer prices are an aggregate of individual pricing decisions made by individual companies every day, vs individual buying decisions made by individual people every day. The market will find its level.
