I agree completely with this statement. I also agree with the first answer -- I agree that many people will work only for the money and that there is nothing wrong with that.
I want to add only that there are many jobs in our society that must be done but that are unlikely to bring self acutalization to the people who do them. I have had at least three that I can think of.
First, I prepared food at McDonalds. Second, I shelved books in libraries. Third, I worked in a factory in which honey was extracted from the frames where the bees deposited it. None of these jobs involved anything that could be self actualizing for very many people.
This means that there have to be people who work only for money. Otherwise our economies would die.
