The casinos could subsidize it, so it might work.
I dunno about this one. Las Vegas is a house of cards. Collapses with a turn of events in the economy. Should taxpayers subsidize gamblers? They already subsidize billionaire sports teams. The people who profit most should pay 100%>. It sounds too much like the Robber Baron Industrial Complex.
The Casinos and all the hotels in Vegas, especially if they allow gambling plus a bar and live TV on the train.
