> Unlike food, gas, houses, movie tickets, and restaurants, the amount of money transacted in wages/salary cannot go down. And when, exactly, looking at 5-years windows has the amount of money transacted for movie tickets, food, gas, etc. gone down instead of up? Not prices from one week to the next or to the next month, when did prices consistently trended downwards for a period of 5 years or longer for a given product?
