Like I said in another comment these types of deals are turning governments into quasi-investors. They put money up front with the intention that decades later it will pay off. What if some of these projects fail before the pay off?

Up to this point these deals have largely paid off. But if this starts becoming the norm, and government leaders start coming under pressure to outbid each other, I fear for what might start transpiring. Elected officials that are looking to score points for the next election are not someone I'd trust making these long-term decisions.
