Judging by what Republican presidential candidate Mitt Romney says, business experience and success in making money make an individual an ideal president. By that standard, rapper Jay-Z would be a terrific leader, Melissa Harris-Perry joked on Sunday morning. "He hasn't just worked in the private sector, he is the private sector," said Harris-Perry, on her self-titled show. "As for being a job creator, Kanye and Rihanna's careers are a testament to his skills in that area." Jay-Z owns everything from a record label to a clothing line to a nightclub chain, she said.
