Point is that can be changed.
Competitiveness in certain things is hard to change. Oil for example:
Geology is the biggest limitation. And you cannot really change geology.
But cars are not a factor of geology.
We could become more competitive via trade policy modifications and investments.
Japan built its car industry on protectionism, subsidies and intellectual property theft as much as it did on innovation and skill.
Again you cannot treat automotives as a free and fair market subject to free trade.
They do not work that way because the successful ones do not play by pure free trade rules.
You have to bend and break the rules to win the game, if your competitors are doing the same.
