Lottery winners have a much harder problem than those with seven figure income. A lottery winner is usually getting a single big lump sum; if you spend too much, you don't get a second chance.

Someone with a large income probably grew their income over several years (although, if you know of any career paths with seven figure starting salaries...), and have had a chance to learn that even though it's a huge amount of money, it's not infinite money. But if you do overspend one year, you're likely getting a bunch of money the next year, so you can probably work it out.

You mean the actual statistics that show that lottery winners’ happiness is enormously improved by their windfall over the long term, and they make sensible investments in their future?

Or the outliers who blow all the money on silly things and make the news but aren’t actually at all representative?
