I ran the numbers. To get to a $15 million net worth, you would need to invest $220,000 a year, every year for 30 years at 5% average annual growth. That is more than a senator makes now. Just running numbers, implying nothing.
Never mind. I was looking at the wrong net worth figure. (Chelsea's, which makes a different point.). I deserve a free, gratuitous flame from you, if you are so inclined).
