Was Solyndra’s failure due to the wrong technology at the wrong time, workforce too costly, lack of demand for solar?

You have a company, Solyndra, the government is touting as their poster boy, and garnishing with half a billion dollars the public is on the hook for, was that a better investment than another cruise missile or drone? If the workers have been able to work cheaper, would the company have been able to stay afloat? Was solar just not popular enough to supply enough demand to cover overhead?
