So much for economic education in this country. :-(
$2,000,000 invested in non-taxable state and local bonds would produce an annual income of $100,000 a year without ever touching the principal. If she invested part of it (say half) in good mututal funds or stocks she would make 10% per year or $100,000 appreciation on just the stock portion and she still would have $50,000 to live on. Then if she got out and worked like everyone else, she would have even more income.
