I do not think that the attitude in Vegas is all that clear cut as being against off shore books, nor even off shore casinos.
True, the state of Nevada has very strict laws regulating gaming. For example, no state lottery, and even when non-profits run lotteries they have to be very careful about how they go about it. And I don't think non profit Bingo is even allowed.
And Nevada does have rules that specifically prohibit off shore gambling of any kind. But, actual prosecution for this offence is rare.
On the other hand, several major corporations with casinos located in Nevada actually looked into also running off shore operations, but this was before the DOJ crackdowns that started a couple of years ago.
Vegas has rarely, if ever, actually been hurt by outside competition. I remember there was all this concern when Atlantic City was opened to gambling. The fear in Vegas was that it would lose a substantial amount of business from the East Coast. For a brief while, it looked like this might have happened to a minor degree, but after a few years, growth of business from the East Coast actually picked up.
Looking back at it, while some customers were indeed lost to Atlantic City, this loss was more than made up for by the number of people who got into gambling having been first introduced to it in Atlantic city, and then later trying their luck in Vegas.
Very similar results have happened over and over again with New Orleans and Indian gaming. And, of course, major corporations with casinos in Vegas also run casinos in Atlantic City and elsewhere.
And its happening right now with Poker. Three years ago Vegas was shutting down poker rooms, and now it is exploding here, despite the huge, apparant "competition" from off shores.
Sports Books are a different story in the sense that Vegas has, indeed, lowered limits compared to many years ago.
But, I do not think that the total money being made in Vegas from Sports Book operations is less now than it was 10 years ago. And, this same "trickle down theory" that applied to Atlantic City, Poker, etc is probably taking place as related to sports betting. The additional interest that offshore books has created has created more people who get into it in the first place, and the next time they come to Vegas they might visit the sports book.
The high limit players don't like it, but I would not be surprised if Vegas' decision to cater to the low and middle level player has actually resulted in a better bottom line, and certainly less risk whish upper management hates, than it was 10 years ago. Vegas is finding its niche in the market and seems to be happy with it.
Also, Vegas realizes that it has always been a rogue in the eyes of the Feds and the major leagues and NCAA. Leaders of the industry here have often said that rather than try to ban it, the government should be regulating and taxing it, just like Nevada does.
I think as the various suits that are going on in the Inernational courts and so forth develop, you will actually see amicus briefs being filed by Nevada entities in favor of the legalization, regulation and taxing of offshore sports betting and Casinos.
We shall see.
