P.Fritz observed:

His whole premise is flawed, since it is based on generating an income
stream solely from investment growth and not from reducing the
principal.

The gross savings required to have a 2k a week retirement is
significantly
less if you withdraw from the principal as well.....

Never, ever, spend the principal.

The idea is to leave that to your kids, so they can blow in on wild
parties, European vacations, cars, yachts, mistresses, and caviar after
your demise. :-)
