There are multipliers for big infrastructure projects but not x292 lol. Unless they’re planning another losing war and are telling arms manufacturers how much they stand to make in he region.

For housing, it could be 10x. by the time the people living in them decorate, but toasters, fridges, furniture, etc. Plus shops being able to find in and set up store. I don’t know too much about it. There must be an agreed timescale for working it all out.
