I'd be impressed if you can link that back to something I said, I don't think my opinion is that at all. I haven't said anything about poor people, for example.
If someone has enough money that wasting it on gambling is a problem, then they clearly had no business giving up hope because "the system" doesn't have the ability to make their lives better. The system that makes their lives better is the money they just wasted, but invested in something productive.
Someone can't claim to be hopeless about the potential to improve their material comfort when the means to do so was just sitting in their bank account. They have money spare - start spending it to make life better.
I'm happy to accept that gamblers are irrational, but their problem isn't that the system is causing them to give up hope, their problem is that they are irrational gamblers. Sucks to be them, but it isn't anything to do with systemic external factors beyond casino advertising which is quite a specific thing and nothing to do with general hopefulness. Or the quite likely reality that they don't know what opportunity looks like despite it being right in front of them.
