Casinos and bookmakers are not forcing, or even trying to coerce anyone into parting with their money. They make enough from people who understand the risks and are willing to trade their money for a bit of fun. Scams are entirely manipulative and criminal in their intent, yet the vast majority of gambling centers are fully licensed and operating in jurisdictions with strong laws. You have to be willfully ignorant and blind in order to associate these businesses with scams. People know they will lose money yet think they are smart or lucky enough to beat the odds, they are not - so get angry when they lose and claim the casinos scam them instead.
