I suspect that if you ask most punters if the house has an edge they would say yes, but if you ask them the purpose of them being there, it's because they want a chance to win big, not because they want to give the casino money. So, sure, everyone knows the house has an edge, but saying that the purpose of legalized gambling is to enrich the casino is a very different claim.
