(Minnesota Public Radio) — Most big companies these days want to boost the number of women- and minority-owned firms they do business with, but the reason has nothing to do with altruism. Big firms say diversity among their business partners helps the bottom line. Last year, U.S. corporations bought more than $100 billion in goods and services from minority-owned and operated firms. Businesses are well aware of America’s changing demographics. Minority populations are growing and by 2050, it’s expected only about half of Americans will be non-Hispanic whites.
