As the story goes, someone asked an economist how his wife was doing, and the economist answered "compared to what?"
Joking aside, this is one of the most important questions one can ask when dealing with many economic problems.
In recent times, with gold reaching all-time highs, we have seen people question the valuation of assets in dollars. Basically, the yardstick used to measure your assets — your house, car, or stock portfolio — is a steadily shrinking one. This makes you wonder whether your savings are really growing in value. In other words, if the value of your savings has doubled, but the price of milk and everything else has roughly doubled, you are not getting ahead. If anything, you will likely have to pay taxes on your supposed "gain," which is no gain at all.
