Cultural monument or boondoggle?

My friends seem equally divided about the benefit of the Carnival Center. Some are ecstatic that Miami finally has a center of this kind. Others think it's a white elephant built for the rich to show off. The latter group is now up in arms over the huge deficit the center has racked up because of miscalculations.
I'm not sure who's right. But I do know this: In a private company, if an employee was so way off with numbers, their job would be on the line.
