To paraphrase Sallie Krawcheck, If you start a business with all left-handed people, your network will disproportionately include left-handed people. This will result in a business that is decidedly left-handed. This is intended to be an argument for diversity in the context of work. Perhaps there are reasons you might want a company that is decidedly left handed. What sorts of industries may benefit from diversity? What sorts of trades/industries might not benefit from diversity?
