At reduced costs there is no reason not to build them, especially at a 54k discount!

I will say that building something at a discount isn't very historically accurate as far as governments go, call me cynical, but I believe the United States government in its entire history has only built 3 construction projects under budget and ahead of schedule. I apologize for getting on my government spending soapbox, and I'm not bashing the historical accuracy of the mod, just the ineptitude of most governments at controlling their budgets... a side affect of studying governmental accounting I guess.
