Price increases are bounded by substitution of goods and "what the traffic will bear."
The things - real estate, education, health care - that are inflating most rapidly are doing that because they are subsidized. When you subsidize a thing, it costs more and you get more of it
Ag subsidies are different because that's a sort of Nash equilibrium - the cost of inventory underruns exceeds the mild price increase from overproducing agricultural products.
If you need to by X, Y, and Z and Z get's cheaper it can only save you so much money. Price increases on the other hand are unbound.
