Anyone who has been through even a minor in business science will have been exposed to the precept of price elasticity/inelasticity. Some products will sell regardless of price, out of real or imagined need/scarcity. EpiPen is a great example. It doesn't matter what the price is as the invisible hands of free markets are hamstringed (crony capitalism) negating supply and demand. The price will be paid regardless and it can be said that such goods are price elastic. Conversely, where the invisible hand is allowed to do what it does (true capitalism), inelasticity will eventually cap a price for any given good.

Pinball machines are very much the latter as price inelasticity will match suppliers with demanders and prices will stabilize at fair market value wherever that may be. What we see today may well be the edge of the market and prices will soon pendulate and normalize. Or not... Market forces are fickle/irrational and not one man in a million can make such a prediction. There are simply too many variables to make an educated guess.

It boils down to what it always does. The percieved value of fiat petro credits in exchange for the perceived value of a good or service, ultimately making the argument moot. One cannot gouge a price inelastic good as value is in the eye of the beholder. The market simply will not bare anything to the contrary with few exceptions on the fringes.

Personally, I find more value in a wooden box of gizmos than I do in a dirty cocaine covered piece of worthless paper. That is, unless I'm short on worthless papers and need an EpiPen.
