Apparently it has escaped the notice of politicians and bureaucrats that the interests of contractors are not the same as the interests of their customers. The contractor wants to make lots and lots of money. The contractor wants to make the customer happy, so it tells the customer whatever it wants to hear: oh sure, we can do that; or oh sure, that’s a great idea, you must be very smart to have thought of it; or I’m sure you’ve heard about the steps being taken by your competition, but fortunately we can stop them. The contractor has no interest whatsoever in completing the work, because that stops the money flows.
