Prime Steak index?

Reading The Big Money today, I caught an item claiming that a decline in steakhouse eating has led to a surplus of USDA Prime steaks.

It seems like only yesterday that The New York Times reported a shortage of top-quality meat for steakhouses — but it turns out that was at the peak of the bubble.

Leaving aside any debate as to whether prime steak is worthwhile, I wonder if we could or should assemble data as to where prime steaks are headed to determine the direction of the economy.
