Seems like it's still being decided whether it is being sold or not? Seems like a nice idea for them to try though. It is going to help their country in the end, and it is a raffle, luck still plays out in the end. Too bad its only for Mexican residents though, which could be said to be a good and bad thing since no countries could take advantage of the raffle.
Well, if you read the article, the government of Mexico needed the money so they are selling the plane. The money they will be getting will be used for the development in their country. As I said, it is not just for the chance of winning the plane but also a chance to help the country. Obviously you did not read the article the OP posted, the president will give the maintenance of the plane for year free. He also thought about those people that might win the plane and don't have the money when it comes to taking care of it. It is true that people can just hog all the lottery tickets but that is not worth it. Even if it is a plane, it is not worth it.
The other guy might be considering it in terms of a "selfish" kind of perspective. I mean, some people wouldn't know what to do with a plane tbh, and if it just sat there doing nothing, even if you got it for a few bucks, it'd still seem to be a waste right? And a year of maintenance, it ain't like you're gonna fly the plane a hundred times per year, so yea. If the Mexican Airport could accept a rent kind of thing with the winner though, it might be much more worth it/helpful.
