Invalid comparison.
The old Soviet Union was void of any market forces whatsoever.
It was strictly a centrally planned "command economy" with all resources owned, controlled and operated by the state.
In contrast, when markets falter due to the pencil-pushing, paper-shuffling excesses of Wall Street, there is nothing wrong with Government "priming the pump" of private industry by building infrastructure that benefits EVERYBODY for decades to come. And I do mean EVERYBODY, private businesses as well as the workers who become their employees. And taxpayers receive tangible and lasting infrastructure for their investment.
