It doesn't "always" go up. It goes up and down - and trends upwards over time tracking inflation, like everything else.

I get what you're saying and sorry to split hairs, but the world "always" means just that - always. At all times. This is not a true statement and an incorrect use of the word.

Generally speaking, if you hold MOST things long enough, you'll make money (in terms of absolute dollars, not necessarily in terms of inflation-adjusted dollars) for them.
