they do leverage themselves with odds and crappy BJ rules...like the fact craps is 2x odds, you cannot maximize the player odds by betting 5x or 10x behind your bet.
With that said, I see the shitty blackjack rules in my local casinos as well...side bets and 6:5 and so on. Casino carnival games are what they are, house edge is always up on 3 card, texas sud, hold 'em and so on....there is a reason they replaced blackjack felt.
Roulette odds can't really change, they can just make you bet more per spin.
So, gamblers beware, but I will still sit at a $10 blackjack game even with CSM and 6:5 because the alternative is not playing...I will play craps with low odds because unless the table is smoking hot, I'm not upping my odds enough to care about the bad back odds.
