I was in Washington during the Carter years and bought my home in New Jersey in 1980. The interest rate on the mortgage was 18.5% and it would have been cheaper to put it on my Visa account! Topped at 18%.
Now to doughnuts. I am not a fan but my wife is. Last year you could buy 2 boxes at a 7-11 for $5.00. Today the same doughnuts, but just one box was $6.99! Try calculating the inflation rate on doughnuts. Remember 1980! It went from $2.50 a box to $7.00! Think Weimar!
