Just wait 15 years when the middle class has been struggling with easily accessible gambling and it can't be explained as problem of character. There will be laws passed and people prosecuted or successfully sued.
Those folks that did fall to it, then became (often) lower class while failing to it.
The thing to realize, is that the upper classes ‘eat their own’ just like any other. It’s why Trump is as frantic as he is, he knows what will happen when he stops being ‘useful’/necessary.
But even if that wasn't a thing - the way it's ruined watching sports now, with the constant odds flashing, etc, I'd ban it JUST for that, on top of all the detrimental effects on society.
I don't remember "I can't throw money away on this football play" being a massive society wide problem that needed fixing in 2010, pretty sure everyone could bet with their friends already.
