Charlie Munger on Gambling

A question about gambling as a business at the Berkshire Hathaway 2007 Annual Shareholders Meeting.

 

Warren Buffett: "Gambling is a tax on ignorance.  It is a shame to see governments sponsoring money being taken from people and their social security checks."

Charlie Munger:  "You won't see a casino in Berkshire Hathaway's portfolio." 

I wonder if this just hurt the valuation of Las Vegas Sands (LVS), Harrahs (HEH) and the other casinos?
