Here's why.
It doesn't matter if you win $600million or $40million, the difference will be unnoticed for anyone here.
More exact, your life wouldn't change any differently if you won the bigger lottery than if you won the smaller lottery.
You would never work again either way. You could get all the toys you wanted either way (Get Flush), You would never worry about money again if you have half a brain, Your kids would be set, No Monthly Bills, You could be a philanthropist, etc...
Yes, if you won the bigger lottery ie $600million you could buy a yacht or a private jet but for most of us, there's a maximum benefit that even $40million would nearly provide.
