Maybe it’s time to buy Larry Silverstein out of his lease, Bloomberg mused to the editorial board of the New York Daily News. Ten million square feet of high-end office space may ultimately provide the highest rent for World Trade Center developer Silverstein, but it will require government subsidies and a potentially long wait because there’s neither enough insurance money nor a strong enough commercial office market to build it all now. Instead, why not get going faster and with fewer subsidies and a different mix of office, residential, retail and public space. “I think it’s time to see what the marketplace really wants and perhaps we can better accommodate that,” Bloomberg innocently remarked.
