This is an old and universal problem. The NFL knows they are running out of "other cities" when it comes to franchise locations in the USA. NFL Europe has already failed, and one game a year in Mexico City, London & Tokyo, does not represent a season(s). This country had had stagnated economic growth for over 10 years, the middle class has shrunk, and the taxpayers are generally in no mood to entertain stadium projects. Vegas has been off limits for years because of the co-located gambling but now we have the Raiders going to Vegas.
Once again the politicians are not listening to the people, and the Vegas stadium, and its debt, will be the result. Can't think of anywhere else where this could happen, right now.
