As is clear from his website Dawkins has succeeded, as this quote from The Guardian shows, in turning his career in Biology into a formidable generator of revenue:
Dawkins regularly goes on fundraising lecture tours, where his fame comes in useful. Tickets for a tour of the US in June —“an evening with Richard Dawkins”, in theatres in Portland, Oregon, Rochester, Minnesota and Boston— are on sale on [Dawkins'] website for $35. Access to a VIP reception beforehand is $250. Membership of the “Dawkins circle” costs from $1,000 to $9,999 a year, winning you discounts to the foundation’s online store ... and, at its most expensive, two tickets for an “invitation-only” event with Dawkins himself.
Although annual membership in his "circle" costs up $10,000, Dawkins could be making "serious" money—millions, not thousands, per year—if he used his persuasive skills more fruitfully.
