Doesn't inflation directly lead to a decrease in the percentage of the likeliness you are going to be able to hit the correct number for the same kind of products?

Also I think Apple and China kinda destroyed the whole "relative value, everything only has a 5% markup compared to their cost" price evaluation model. You know the thing that used to allow people like our Grandparents to be able to afford things like the American Dream on a single poor person's salary.

That's my theory anyways. Or maybe people are just getting lazy and not studying as hard as they used to. Or perhaps Bob Barker finally kicked his cocaine habit and no longer needs to keep taking the bribes?
