The point was that this shipbuilding industry, critical to national security, was protected by subsidies until President Reagan left it to die.Who could have imagined* that, if left to its own devices, the private sector would choose not to do things that are not as profitable but are nevertheless in the national interest? And that in the long run, we would suffer as a result?

Subsidies , tariffs and whatever else is necessary should be used to return critical industries back to the US and override the economists and free traders.
