Are they? Because I would expect far less complaining about the economy if this were true.

You can't rebuild an industrial base overnight. Industrial supply chains and cultures of expertise take time to take root. That means not just some abstract incurred cost, but a very much felt burden on the average citizen. And with a weakened economy, it's difficult to see how this industrial base is supposed to materialize exactly.
