Sometimes Miami-Dade County needs a reality check. Learn to budget your money wisely — you can't put everything on credit and expect it to work out in the end. The county learned this painful lesson when the under-construction Patricia and Phillip Frost Museum of Science, like an entitled trust-fund kid living in New York, announced it had run out of cash. The museum ran back to the county saying it couldn't afford the monthly $5 million payment to the construction firm. Commissioner Xavier Suarez called it "a comedy of errors," but it was hard to find the humor. Perhaps that's why the museum's namesakes, philanthropists Patricia and Phillip Frost, swooped in to help finish the project. It wasn't the first headline-grabbing act of charity courtesy of this power couple, whose fortune comes from a pharmaceutical empire. The Frosts have given $33 million to the University of Miami's music school and funded scholarships at Oxford. But this may have been their most resounding move. In exchange for their project-saving cash, they canned nearly the entire board of directors. Then they insisted the bailout would be only a bridge loan until county bureaucracy could free up the funds. The county finally approved the $49 million bailout in April, though that money comes from cash that was supposed to help the museum operate once it's open. Let's hope the Frosts are willing to lay down the law to push the city's other elite to help if funding goes sour again.
