Inflation doesn't mean income goes up (unless your job contract guarantees inflationary increases), it means prices increase. So while his mortgage may be fixed, the prices of all other things will increase, while (more than likely) his income will stay flat. It's not a recipe for eliminating debt, so he shouldn't be cheering that scenario.
