Well, I would assume apropos of my one economics class that the reason the average person doesn't care too much about inflation is that he has more debt than assets. If you ask me whether I want to pay a lot of taxes on my income or whether I want a big slice of my house to be free in inflation-adjusted dollars, here we would be, assuming I had no assets and most of my income went to my home loan.
(Right? What did I miss by not taking Econ 102?)
