From the 70's through the 90's, the US inflation rate was around 5-8% per year, peaking at 13%
Since the 2000's, inflation has decreased towards less than half a percent

Meanwhile, the costs of healthcare, housing, and education have ballooned (say, for the sake of argument, 4-fold).
Over 20 years of ~7% real inflation, that's a factor of (1.07^20 = 3.86)
Doesn't this mean that housing, medical, and education costs are, in fact, what they should be, and only wages and commodities have been stagnant?
