What impact does a pluralistic society have on business?

The impact that a pluralistic society would have on businesses is good in the sense that there are different cultures living in one area. For example, in Pennsylvania, there are many small Amish towns, as well as normal cities surrounding them, the impact of the Amish people and the English people as they call it, is great since the Amish can sell their items to the businesses of the English people, giving the English businesses much profit and the Amish get the business from the English. Without such a society, English and Amish businesses would decline in finances, since the English need to pay little for Amish items and the Amish make out nice financially.
