They don't go back down completely, but they do go down. In the 1980's, I believed that no bank would ever go back to 2% or 3% mortgage rates when they were used to 12, 13, 14%.No they will not. Point a time after there was a round of inflation to where the prices went back down to where they were, it never happens.
Companies have gotten us used to paying the higher prices, they have no reason to lower them.
I was wrong. You probably are too.
