KAI RYSSDAL: The federal minimum wage went up today. It was a 70 cent bump to $7.25 an hour. Workers at the bottom end of the pay scale in 31 states will be getting raises. The other 19 states already had minimums higher than the new federal standard. The increase had been in the works for a while. It's the last of a three-step adjustment that was started years ago. It just happens to be coming in the middle of the worst recession in 75 years.
