The last I heard is that David Icke is an extremely wealthy man.
He didn't become wealthy by being a sports presenter or a mediocre goalkeeper, so I can only guess that his extreme nuttery is very well paid.......as was L Ron Hubbard's.
Obvoiulsy you can't compare the too - David Icke hasn't founded a cult, but it just goes to show how people can spout the most preposterous pony and make an absolute killing.
