there's no evidence to even support your lottery bankruptcy stat

Literally the first article you cited makes note of the fact that all of the previously published literature found no evidence that people became significantly happier after winning the lottery (links are provided there so I won't repeat them here). Unfortunately I cannot read the rest of the article since it's paywalled.

In the second study, the vast majority of the sample consists of people winning smaller sums (over 80% won less than $200k, which is certainly enough to fix the most pressing issues in your life, like a leaking roof or being behind on rent, but likely not enough to build a foundation for long-term wealth). Also, consider that this happened in an environment where the average person did NOT win the lottery, which is important because a massive shift in wealth distribution could have a significant effect on demand curves and would likely cause a huge change in market prices for nearly every good on the market.
