Carol Costello: How have your views on the roll of corporation and purpose evolved over time? And what do you make of the shift towards purpose? She says she was fortunate to work for the founders of home depot, burney marcus and arthur blank. Costello: They lost 13 billion dollars of revenue in one year, 25 % of their top line. But they also decided that even though it was the depth of thea recession, we were going to invest in our people.
