Not really, when Black Americans and other minority groups that grew up in poverty rise up in economic status they actually get fatter. Not sure where the statistic on it is but it was a really interesting find.
There are more calories in cheap foods. This has gotten worse with processing, but from where I can see, no obvious solution exists.
Because that’s who they are. The lottery doesn’t change your character it reveals.
Or perhaps it's not really a character thing at all, as the cheapest foods these days are high-calorie and engineered not to satiate.
A fair amount of the lottery is family wealth at birth. And while it's just opinion, I believe that alcoholism has more to do with circumstance than character. There's certainly more access to treatment if you're wealthy too.
