Actually, it's worse than that, if you read the article.
NY Government (Governor Andrew Cuomo): Let's build a new subway station. Hey MTA, why don't you negotiate for us and figure out how much it costs.
MTA: Hey TWU, you can figure this out for us, right?
TWU: Hey contractors and vendors. How much will it cost us to have you supply parts and do some of the work for this project?
Contractors/Vendors: Oh, that'll be $500,000, which allows us to make a healthy profit margin of 20%.
TWU: That's not enough - you should be charging us $800,000, so we can make a healthy margin as well without cutting into yours.
Contractors/Vendors: By golly, you're right!
TWU: Also, add another $200,000, because we need an "operational readiness" consultant to help us when we're ready to finish. The project won't be ready for another ten years, but we should employ them the whole time just in case.
Contractors/Vendors: Sounds good to us. We're not the ones paying.
TWU: Hey MTA, this will cost $1,450,000. We added on an extra $450,000, because they're using a fifty-year-old piece of technology, and our contract stipulates that we get an extra $450,000 every time they do, to offset the job loss from this "technological advancement".
MTA: That sounds like a reasonable price for this. Hey Cuomo, you're the governor of NY. Can you please rubber-stamp this proposal to increase our budget by $1,450,000? Look how strapped for funding we are.
NY Government (Governor Andrew Cuomo): Well, you supported my last election bid, so I don't see why I should start questioning your prices now. Let's go!
...seriously, read the article. This isn't even an exaggeration.
