When hamburgers go down in price, we sing the 'Hallelujah Chorus' in the Buffett household. When hamburgers go up in price, we weep. For most people, it's the same with everything in life they will be buying– except stocks. When stocks go down and you can get more for your money, people don't like them anymore."

He's right. Any rational human being actually LIKES falling prices.

We enjoy getting a great deal, and we like it when our money goes further.

To Buffett's point, investors are a major exception and prefer investing when prices go up, i.e. their money buys less of a high quality asset.

But there's one more giant exception that Buffett didn't mention: economists.

Economists quiver in fear at the prospect of falling prices.

They call it 'deflation', and it's a force so dreaded that central bankers have threatened to drop bricks of cash from helicopters in order to prevent it.

Instead, economists prefer INFLATION, i.e. that the things you buy become more expensive.
