Inflation doesn’t affect rich people as much. Food costs for a £100k earner aren’t 5x what a £20k earner eats, or needn’t be, and rich people often own assets that are inflating with inflation.
It's not good if you are asset rich but cash poor. Eg a retired home owner planning to live off cash assets which are not increasing in value as fast as your bills.
Of course you can equity release or downsize or something but you still aren't going to be happy with the higher interest rates.
But not if interest rates are below inflation.
