I agree that selling skills are very, very important and useful. However, I think there are so many other useful business skills you can use, too, to help get in full control of your life (and increase your "survival" options).
Some other skills which come to mind are recognizing and making good deals, including negotiating, how to get free publicity, and also motivating others, knowing how to hire the right people or outsource... and I'm sure there are plenty more...
However, I agree with you - if you are good at selling, you can always make money...!
