OK, Adam, imagine you are sitting on a chunk of cash because you sold your house at the top of the bubble.
Because you have read this site, you realize that real estate is going to be a bad investment for a while. Therefore, you decide to start your own business - Adamco.
Because Adamco is a new business, you research the market for your product or service. And if you do your research well, you find that in the (hypothetical) deflationary environment you are in, by the time you are ready to provide your product or service, the price for that product or service will be lower than it is today.
This causes a problem because you have to get an office (or factory) and computers (or machinery) and employees at today's prices. But by the time your business is ready to meet an unmet need, you'll be selling those goods and services at tomorrow's (reduced) prices. You may not be able to make a profit at tomorrow's reduced prices. Or if you could, the profit would be lower than what you would make if we weren't in a deflationary environment.
So you ask yourself "Why not just wait until next year to start Adamco? After all, I can build the same business cheaper then."
And you could.
But if deflation still hasn't been broken, then putting it off another year next year makes economic sense too.
Therefore you don't hire any direct (or indirect) employees to get Adamco off the ground.
The deflationary conditions that cause you to postpone the start of Adamco aren't unique to Adamco. They apply to every existing business and startup of someone's dreams. And as a result, a lot of people don't get hired for direct and indirect jobs.
It's the kind of thing that spirals on itself.
Looked at the numbers I posted earlier. The Great Depression was the last deflationary cycle this country has faced. Unemployment was 25%. Wages of people who stayed employed fell 42%. GDP was almost cut in half.
I'll take inflation any day over deflation. (And yes, that would apply to a hyper-inflationary environment too)
