He was earning big bucks, by anyone's standard,at that time, so spending money for something wasn't the problem! Yet he had NO interest in doing any but sitting at his computer and/or "preparing" for the next day's show...which, truth be told was far better back then, than it has been in decades.
And with your attitude about money and not paying attention to a wife, I doubt that you are in any kind of happy relationship.
Again, why should he pay money to do things if he didn't want to? Apparently, his show required research that he may not have wanted to pay people for in those days.
