Now the burger cost goes up, and working people have even more money than "normie" millionaires. I imagine people are going to be more free with their money, so they pay more for the burger. And this will settle, per the law of supply and demand.
That part is obvious.
What is not clear to me is how the new price would work out. Maybe it would work out to pretty much the same relative cost it is today, but in inflated dollars. And the rest of the market is doing the same thing. And landlords know you have the money. The squeeze comes back. Cue Econ 101/102.
