Have any data to back that up? Comparing a democratically run corporation to the US government is a non sequitur. Outside VC there is no business model that will allow you to run at a loss for decades. So it's a scenario that's not even possible hypothetically.
Somewhat anecdotal but there is a Worker Co-op in Spain, Mondragon, that's been a very competitive corporation for over 50 years. It can clearly work long term and it leads to better outcomes for employees and the communities they work in.
