Panama Construction

I am in Panama City for the annual SECOLAS conference. What immediately strikes me is the construction. Of course, the canal is being widened, but a new metro is being built, the old part of town (Casco Viejo) has tons of work being done on it, and there are high rises going up. There is work being done all over the place

My first thought was debt, which may well be the result. Somone has to be paying for all this.
