I just re-read Zenna Henderson's Pilgrimage: the book of the People. Published as a paperback and sold for 75 cents!!! Paperbacks now sell at about nine dollars.
Minimum wage has also gone up. And every time that goes up, corporations jack up the prices of everything. Meaning that no matter the raise in income, the equivalent cost of living remains the same.
How are we going to stop this constant spiraling upwards?
