If someone won millions from the lottery, say, 5 millions, and spent 4.5 millions "just to have fun", as you said, I personally don't see anything wrong with that. Imagine it was a rule: only if you win big money you can spend it on yourself, or, on anything you want. Only in that case, the case of winning a huge amount. Otherwise you should just work and spend money on your family. We would have millions of happy families, wouldn't we? Unfortunately, people don't have any money and they borrow it and spend "just to have fun". That's a problem.
