The Purpose of a business

[Blurock]

What is the purpose of a business?

Nine times out of ten I get the answer, "to make money."
Is this why some entrepreneurs try to take shortcuts, supply sub-standard materials and inflate prices?

The question is; where does the money come from?
Obviously from customers.

So should the purpose of a business not be to create a customer? Once you have created the customer, the next step is to retain the customer for repeat business.
So how do you retain a customer and keep them happy and coming back for more? (and also tell their friends).
