They're both true. Sometimes the supply and demand curves don't meet.

I think this is incorrect.

Supply and demand curves _ALWAYS_ meet. It's just that the point where they meet tells you what the market-clearing price is.

Sometimes this information makes one sad.

Managers who "can't hire good people" are sad because good people cost more than they want to pay.

Employees who "can't find a job" are sad because jobs that match their skills and other requirements pay less than they want to receive.

"I see what you did there," as they say elsewhere on the Internet.

Nifty little device to make a an important point.
