This is ridiculous. First, it's untrue. Ask Dre or Jay-Z. More importantly, since when is "transformative wealth" hundreds of millions of dollars? If you grew up truly poor and uneducated, making a steady $80,000 a year -- decent house, raise a family, put a little away -- is a transformation.
The odds of ending up like Dr. Dre or Jay-Z are worse than the lottery and require even more significant time and monetary commitment. You’re better off going with your latter suggestion of trying to make a decent living which has pretty good odds.
