Is it a surprise that tax evasion is a giant problem in Italy? Well, it shouldn't be, when the Prime Minister is the biggest culprit of tax evasion.
I guess he follows the old adage 'do as I say, not as I do.' Good thing too! If we were all like him we would cheat on our wives with prostitutes and 18 year old girls, have orgies in Sardegna (that were photographed, no less), and call all our opponents poor communists, in addition to cheat on our taxes.
