Why Golfers Get Ahead

That's the title of an interesting article I read on the Economist tonight.  Here's the hook for you golf business owners:

A recent study shows that bosses who don't play golf get paid on average 17% less than bosses that do play golf.

How's that for a marketing campaign for your golf facility.  Come play golf and get a huge raise.  Sure, that's not how it actually works, but interesting empirical evidence shows that what golf teaches you helps you get ahead.

The article attributed the pay increase to more schmoozing, but I choose to believe that it is because of the virtues of the game develop character that helps develop better leaders.  What do you think?
