Though this is conflating correlation for causation. As you note yourself in GP, dire social conditions is what makes people see gambling (or risk-taking more generally) as one of the only viable options to get out.
In this case, I can agree bad social conditions cause gambling, but I don't think the data supports the opposite, at least not more than many other things we take for granted, such as
- alcohol,
- beauty/fashion industries,
- social media,
etc.
Do you deny that those observers can correctly identify the substance or the activity that the addict is addicted to?
Do you deny that addiction is quite deleterious both to the addict and to the people with whom the addict is in some kind of relationship?
Many news stories claim that many Americans (young men particularly) are getting addicted to online sports betting. Do you dispute the accuracy of those news stories?
If so, can you guess as to the motivation for publishing these inaccurate news stories? Often a campaign to mislead the public is done because some group would gain something quite valuable if the campaign is successful. What would any group have to gain (aside from a slightly healthier country) from a successful campaign to make online sports betting illegal?
We need to help these people, but we do not help them by driving their vices underground.
