Greatness by Putting Yourself Out of Business

You may not be aware of this, but Dentists should be viewed as selfless heroes.  They are furiously trying to put themselves out of business.  They have been for years - getting fluoride in water, improving preventative care, etc.  And theirs isn't the only occupation that behaves like this. 

I recently had a procedure that went so well I told the doctor he was too good - he was going to put himself out of business.  He said he has to try to put himself out of business - if he doesn't, someone else will.  That statement pretty much captured the essence of the stunning success of capitalism.

This, of course, is the complete opposite of how government employees work.
