Never underestimate the stupidity of the American public
Years ago, Vegas catered to gamblers and their business would fall off when they drastically changed rules to favor the house.
Today, the Strip, no longer totally is devoted to the gambler. They have changed themselves into a vacation and convention destination, where Claude, Maude and the kids can see water work shows, volcanos and a pyramid. They also have the status hotels, where you can say you stayed at the big B, Mandalay bay, etc, saw museum status art and a bunch of big fish. These people are not advantage players, it is hard to even call them gamblers. They have no clue as to the odds, advantages and ways to play most of the games they play. What they generally have is a budget, an amount they are willing to loose with little or no real expectation of winning. Basically, these casinos have decided to extract that money from these people in less time, making their profit with less salary cost.
There are still some places that also want the real gamblers action. Some of these only want to bother with them at higher limits and others at lower limits. The gambler will search out the better DD or shoe game, while the tourist will plop down in the first chair they see. So a place like Wynn's has the bad games up front and the good games harder to find towards the back. The MGM's first pit is h-17, but walk towards the back and you find, as low as, $10 S-17. You do not see CSM's in high limit rooms, they are out front, on the bad games to again extract that petty cash as quickly as possible.
6/5 is generally played by people with little knowledge of the game and no desire to educate themselves. They are there to get their free drinks and donate their daily gambling budget while hoping to get an occassional thrill.
Unfortunately, I do not see 6/5 disappearing. Table games on the strip, especially at low stakes, is just not as important today to the casinos as slots and room rates. As long as players do not care, bad games will be there to fleech them faster.
