The risk of reliance on a big outside vendor for a big project in a small town is easily described:
The vendor will be everywhere initially, will purr contentedly during work, but disappear quickly after the final check clears.
It will want the money, will say anything to get it, but without any respect for those paying the bill.
The vendor will – falsely – assume a superiority over those local officials with whom it deals. Those local officials will – falsely – assume the vendor’s genuine respect and partnership, and so will lazily forgo due diligence over the project’s terms, work provided, and consequences thereafter.
It shouldn’t be this way; it often is.
