LAS VEGAS – The Manny Pacquiao Show rolls into town next week, yet another in a long string of pay-per-view fights in this gambling mecca that have added hundreds of millions of dollars to Nevada's economy. Pacquiao's rise more or less coincided with the economic downturn that began in earnest in 2008 and saw many businesses go under and many residents lose their home. Las Vegas was one of the cities most negatively impacted by the recession, and without the economic activity generated by Pacquiao fights against Oscar De La Hoya, Ricky Hatton, Miguel Cotto, Shane Mosley, Juan Manuel Marquez and Timothy Bradley from 2008-12, who knows how much greater the devastation might have been.
