You’re not really correct with that statement.
Most large farms produce almost no local benefit. They don’t buy supplies locally, or sell the product locally, and these days they don’t employ that many people either.
Datacenters are not empty, they still employ people after being built.




Not an engineer but vinegar (ascetic acid) at full strength applied early enough during curing could be a problem. If it’s the watered down stuff for home use and the concrete was already partially cured it wouldn’t do almost anything.
