That decision has been made; that ship has sailed. The casino megacorporations have decided that the avergae Joe/low roller is not worth having in their neon palaces. They've been on a relentless price hike crusade, couple with a reduction in service; when they lost 20% of staff due to the pandemic shutdown, they decided to stick with that staffing level. Saved them money; made service crappier when the casinos came back to life.
They've been thinking long-term. They took the gamble that rather than telling Vegas to go farkle itself, addicted gamblers, craving their Vegas jones, would come roaring back and pay whatever was demanded of them, from insane room prices to high table limits. They were right.
So the bean counters (I hate to dignify them by mentioning their pseudo-degrees) have crunched the metrics, as you say, and determined that high, high prices and shitty service result in a better bottom line. In other words, fewer but fatter customers. They don't give a flying crap about you and me.
Which is why I visit once a year, on my way to somewhere else, instead of six to eight times a year, as I used to.
