(Bloomberg) — Strayer Education Inc., a chain of for-profit colleges that receives three-quarters of its revenue from U.S. taxpayers, paid Chairman and Chief Executive Officer Robert Silberman $41.9 million last year. That’s 26 times the compensation of the highest-paid president of a traditional university. Top executives at the 15 U.S. publicly traded for-profit colleges, led by Apollo Group Inc. and Education Management Corp., also received $2 billion during the last seven years from the proceeds of selling company stock, Securities and Exchange Commission filings show. At the same time, the industry registered the worst loan-default and four-year-college dropout rates in U.S. higher education. Since 2003, nine for-profit college insiders sold more than $45 million of stock apiece. Peter Sperling, vice chairman of Apollo’s University of Phoenix, the largest for-profit college, collected $574.3 million.
