No, seriously, why do they? It’s not like the construction workers don’t get paid their wages if they aren’t given such projects, and, unless you are buying the resources from overseas, the only cost for the construction materials for the state is wages/salaries of the workers who are involved in the relevant processes.
Am I being swindled?
I think the premise is you’re a tiny as fuck micro-nation in the Eastern Bloc that was literally just a few villages before WWII, so yeah you’re improving a lot from the rest of the USSR.
