Suppose you want to collect taxes from restaurants, both legal and illegal, in a way that’s automatically enforced by customers. What do you do?

Well, you simply create a national lottery, so that for every euro you pay you can receive one euro worth of scratch tickets of the lottery. People will go crazy and require tickets when they pay. In the end restaurants will have no choice but to acquire those tickets from the local taxation authority (and pay them in advance!). Believe it or not, this brilliant trick has been implemented by Chinese government and works like a piece of cake. I think it would be perfect to displace escape in Italy. In the picture you see a 1RMB lottery ticket.
