Yeah, I am not really interested in his income totals. Good for him, if he was able to have that kind of success from such a relatively small niche. But, at the same time, it may have confirmed in his mind that his harsh and uncompromising approach was the key to success. And now, he is seeing that there are a lot of things that money cannot buy: common sense, wisdom, a sense of proportion... and common sense.
It may be that his most pressing concern is not that the money will run out, but that he'll have to dish out half of it to his wife (possibly his soon-to-be ex-wife) and kids. And to really bad lawyers who've never written an English-language cease-and-desist letter before. And maybe even a defense lawyer or two.
