Earlier quoted context omitted.
Prices can be very, very sticky? In my city it appears (to my uninvolved eye) that several levels of floor space sublessors need to run out of lessees by raising prices in order to pay (possibly their debt to) the higher levels, with a couple months’ latency for each, until retail can reasonably exist again.
If they start raising prices then CPI will start reflecting true inflation, and we can't be having that!
And everybody’s prices are sticky, it’s seemingly part of how we define fairness. (See the haircut comment two levels up for an example from the consumer side.) I’m certain economists have loads and loads of strong words to say to all of us about this behaviour.
