Yeah, throw your model at: "contractors took six months longer than expected to finish the kitchen"

Extrapolate that out a hundred thousand times and you get a sense of what they were trying to manage. How did they predict remodel costs? Pre-pandemic material costs and back-of-the-napkin labor estimates?

It's worse. These people are relying on unskilled labor hired by contractors to fulfill requirements they dreamed up in a game of telephone.

Mobilizing professional contractors is very difficult unless you are the highest bidder. And even then, shit happens...a lot.
