People have a strong and well-founded attachment to nominal values in the economy. You pay your rent or mortgage with a fixed quantity of dollars, so as a salaried employee certain pay cuts are intolerable, so employers balance their falling nominal revenues with layoffs instead of pay cuts.

These nominal agreements are significantly less flexible than real-valued ones; people are much more able to buy fewer steak dinners when they're $20 instead of $15, and much less able to stay in their house when their paycheck is $1500 instead of $2000.
