Home Depot co-founder Kenneth Langone speaks on this week’s “Wall Street Week” about his background in investing, his feelings on interest rates, and some strong attitudes about the 2016 presidential election. “The thing that bothers me, when you mess with nature…leaving interest rates effectively at zero is messing with nature,” says Langone. People need to be rewarded for investing and taking on risk, and markets shouldn’t be distorted by low interest rates, he says.
