"The initial cost estimate for the system was $25 billion over 12 years; it ended up costing $114 billion and taking 35 years to complete."
$114 billion over 35 years... Is that all???
Heck, we can afford that pretty easy... It's a LOT less than what it cost us to bail out the banks that were "too big to fail."
The main point was the prediction vs. the actuality of the cost.
