Certainly, whatever discussion in class has emerged should be the guiding principle in your answer. As business leaders "spread" cultural values and objects of the United States, economic growth is not that far behind. For example, when Starbucks or Coca- Cola expands their reach into new markets, there is a spreading of U.S. Values because these companies are so closely aligned with the United States. However, there is economic profit that follows with such an embrace. This is the reason why business leaders are quite happen when popular culture expands. On the flip side of this coin would be the fear of those who believe that the spreading of the U.S. Culture and Western values helps to take away from indigenous values. This is a balance that has to be navigated in an increasingly global world. The acceptance of new values does not have to come at the cost of old or traditional ones, but to critics, this is the paradigm believed or submitted.
I imagine that your book or your teacher has a specific answer in mind that you are supposed to produce, so you should probably look for that.
In general, though, business leaders in the US would have been all for the spread of American popular culture. When American popular culture spreads, demand for its products spreads too. There gets to be demand for blue jeans and for American movies, for McDonalds and for the NBA. All of this would look good to American business leaders.
Critics abroad would have called this "cultural imperialism" and seen it as an attempt by the US to impose our culture and destroy their own cultures. France in particular fought against this sort of thing with efforts to keep English words out of French and protests against McDonalds and the Disneyland that was built in Paris.
