What's the Difference Between Being Pro-business and Being Pro-market? In a recent interview I watched a economist say something along the lines of:

"There is a distinction between being pro-business and being pro-market. There should be rules in place so that businesses can compete in a way that is good for the economy and not just good for their shareholders."

Question: What is this distinction exactly? In other words, what is he probably referring to?

The only thing that comes to mind when I think about that statement is how many corporations are using large amounts of profits to buy back their shares as opposed to investing in capital. Am I on the right track, or is there more to it than that?
In a nutshell, pro-business policies help currently existing businesses and their shareholders. Pro-market economies are those that follow the tenets of the free market - competition, no barriers to entry and so on. Pro-business policies may not imply a pro-market environment.
