Big public construction projects are rarely about solving the problem they claim to solve.
That is the sales brochure. The glossy rendering. The artist’s impression bathed in warm sunlight and populated by suspiciously happy pedestrians carrying reusable shopping bags.
The real purpose is usually far less romantic.
Large public projects exist to move money.
They exist to justify budgets. To create spending streams. To manufacture reasons for ever-larger appropriations and ever-larger administrative empires. They create opportunities for consultants, contractors, subcontractors, advisors, experts, oversight committees, review boards, environmental assessments, public engagement exercises, communications teams, and an entire ecosystem of professional middlemen feeding from the same carcass.
The project itself almost becomes secondary.
What matters is that the machine keeps turning.
Politics, after all, is not merely the allocation of resources. It is the allocation of favors.
A sufficiently large project creates opportunities for everyone involved. Politicians gain visibility. Bureaucracies gain relevance. Contractors gain revenue. Consultants gain invoices. Lobbyists gain access. Entire networks of mutually beneficial relationships emerge around the promise of concrete, steel, paperwork and public money.
Once that process begins, stopping becomes extraordinarily difficult.
Because by then the project is no longer a project.
It has become an ecosystem.
Kickbacks may have been paid. Promises may have been made. Comfortable positions may have been created. Future careers may already depend upon successful completion. Professional reputations may have been tied to outcomes. Public statements have been issued. Press conferences have been held. Smiling photographs have been taken.
The machine has already consumed the first course.
And bureaucratic machines are notoriously reluctant to spit food back out.
That is why killing a bad project is often far harder than launching it in the first place.
By the time evidence appears showing that the original assumptions were flawed, the need overstated, the demand imaginary, or the economics laughable, too many people have become invested in pretending otherwise.
The project may be dead.
But dead projects rarely stay buried.
They become zombies.
They shuffle forward on inertia, political embarrassment, sunk-cost fallacies and institutional self-preservation. Everyone involved knows something is wrong. Many may even privately admit it. Yet the project marches onward because acknowledging reality would require someone important to admit error.
And admitting error is one of the rarest commodities in modern governance.
Imagine the consequences.
Imagine a politician explaining that hundreds of millions were committed unnecessarily.
Imagine a senior official admitting the forecasts were fantasy.
Imagine consultants acknowledging that the expensive reports they produced were built upon assumptions that collapsed on contact with reality.
Imagine the public asking uncomfortable questions.
Worse still, imagine accountability.
No wonder the zombie keeps walking.
This is why so many public projects seem immune to changing circumstances. The facts can change completely while the project itself continues advancing with all the determination of an avalanche.
What began as a transportation project becomes a jobs program.
What began as a jobs program becomes a climate initiative.
What began as a climate initiative becomes a social justice initiative.
What began as a social justice initiative becomes a matter of civic pride.
The justification evolves continuously because the original justification no longer works.
But the money must keep moving.
The city of New York is hardly unique in this regard. Every country, every region, every municipality eventually develops its own collection of sacred infrastructure relics. Projects that survive not because they are useful, but because too many powerful people have become emotionally, politically, or financially attached to them.
By that stage the outcome barely matters.
The beast has already digested the project.
The gears have already turned.
The patronage has already been distributed.
The careers have already been built.
And so whatever expensive monument to bureaucratic momentum emerges from the process must somehow be dragged across the finish line, regardless of whether anyone still needs it.
Because the alternative would be far more dangerous.
The alternative would require consequences.
And consequences remain the one public utility modern institutions seem least interested in constructing.
