Real-estate mogul and reality TV star Donald Trump is no stranger to the spotlight — but he can’t be reveling in the attention he’s receiving now. On August 24, New York Attorney General Eric Schneiderman sued the Trump Entrepreneur Initiative, a for-profit school run by Trump, claiming that it tricked students into paying thousands of dollars for courses that failed to provide promised instruction on real-estate business techniques. If these allegations are true, it’s a warning that at least some of what purports to be nontraditional for-profit education can be an old-fashioned rip-off.
