I don't even know what your point is. Sure, almost everyone in the world would be set for life with 4m. It's still only enough to provide means for a very modest life with dividends in cities like Boston, LA, NYC...
We usually successful performers burn through their monies quick because with no need to work, you can blow cash REAL quick. Few are so disciplined as to live on something like 4m forever if they weren't brought up with wealth and the understanding to live frugally.
