I don't know though, in real terms, lots of things have really gone down in price.
Washing machines, TV's, cars, etc., clothes, bedlinen, towels, furniture all those domestic things, have all gone down in price.
Even in the last 5 years or so, there has been a dramatic drop in prices for various things imo. I was in IKEA the other day and noticed how the sort of tables which were £400 5 years ago are now £200.
And the price of food relative to income has also dropped (except for the poor, of course, who spend a larger percentage of their income on food than the rich).
Fuel has gone up, but no higher relative to income than it was 30 years ago.
Nothing has come down in price so much as to outweigh the astronomic leap in housing costs though.
