Quote from sprstpd:
By then your nice return on your money market fund won't be so nice in terms of inflation eating away at it.
True. I agree that money markets probably aren't the greatest choice.
Here is Warren Buffett:
My own preference -- and you knew this was coming -- is our third category: investment in productive assets, whether businesses, farms, or real estate. Ideally, these assets should have the ability in inflationary times to deliver output that will retain its purchasing-power value while requiring a minimum of new capital investment. Farms, real estate, and many businesses such as Coca-Cola (KO), IBM (IBM), and our own See's Candy meet that double-barreled test. Certain other companies -- think of our regulated utilities, for example -- fail it because inflation places heavy capital requirements on them. To earn more, their owners must invest more. Even so, these investments will remain superior to nonproductive or currency-based assets.

I have gold, you are hungry and have no food, but you have a car. I give you half an oz of gold for your car. You take that half an oz of gold and go to the farmer and give it to him for a decent amount of food. The farmer wants gold because of the inflation. He will not take the US dollars because he knows they will be worth less next week while the gold will hold its value against his crops.
