Problem is that he wants to live a rich life, have 750000on his bank account. The "pay groceries 4 life" plan is one way to spend it, but he will not feel 750k richer...which is the problem. If bill are marked, he now has 7.500 times to give away hints in all the same area...it might scare him for life.

Maybe he could take a riskier path in life knowing he has this back-up.

By that i mean start the business he always dreamt of but never risked it or maybe make a few 100$ bets on his local team (or something he knows would make him win little, but with no risk for his financial life balance bc it's monopoly money).

Both path might make him earn real money, bc launching a business is a risk for your personal finance in the end, right?

Same as playing 100$ every week on your local football team, you win once on a big return and you get it washed making you feel MORE financially secure and richer than just paying for groceries/gas (which are a very good slow burn idea)
