Probably offer free parking for LV locals and members of their Casino. I don't see why they wouldn't charge non-members or people out of town. If you can't afford the $10-15 to pay for parking then the likelihood of you going in there to blow your money is reduced.
It's actually a great filter: it makes sure that people are already financially committed and keeps away tourists that don't want to spend.
