While your statement maybe true about the mobs use for Vegas, the reality is the town in many ways was FAR better off under the Mafia. Far less crime (street crime, didnt want to discourage visitors), better treatment for Casio Workers (if you actually worked, not just put in time). That is why there is alot of nostalgia for the mafia days in people who lived through it.
I was born in Vegas, and it has changed drastically over the years, and not for the better. Once the large corporate entitys moved into town, it was pretty much a forgone conclusion. The Egos of management were on line and the constant push to be larger (or better in their opinion) pretty much killed the town. Everyone knew we were building ourselves out of business. Bigger casinos DO NOT necessarily mean that you will get more business, but it will mean you have more expenses and will mean more debt.
Vegas thought it was recession proof. And it was to some extent in the old days (before a massively linked global economy). In the old days when the US economy was down, Asia or Europe was generally up. With the tied economies when the crash came in 2008, business took a massive dive. I wont even get started on the real estate issues of Vegas. I still wont touch commercial real estate in that town. Their is way too much property sitting empty rotting. Whole strip malls, office buildings are sitting empty, fenced off, being stripped of copper wire and played in by children in this town. You learn to ignore property for rent or lease signs, they simply become part of the landscape.
