Inflation shrinks the present value of that debt, without requiring the government to cut spending to pay it down, which would have serious economic consequences (see: austerity).
holding cash is paying something for the first time in more than a decade
Park your cash in a 5% instrument for a year and you can still afford 3-4% less stuff than you could at the beginning of the year.
That's fine for me with a mortgage, but less retirement headroom for many older people.
I personally have a hard time going out to a restaurant and getting a 2 person meal for less than say 30-40$. Car market is absolutely through the roof. Housing market, although cooling slightly, is still through the roof. Our base rent went up 15% last year. Gas is now double in my area.
People will be in between any of the above situation simultaneously, but between having to get fired and seeing costs go up a little at a time, I imagine most people will defer the gut punch and take the erosion of spending power.
