I remember half of the neoclassical economics focused articles about China from the late 90s and early 00s predicting that by not following ricardian comparative advantage China was shooting itself in the foot.
They kept predicting collapse, too.
Nobody talks much about the ricardian theory of static comparative advantage today. China's rise kind of invalidated it.
America was taken by surprise by its rise because of this. The cordial relations and trade flipped almost overnight to hostility once it was realized that China's economic power now rivaled that of that of the US and was poised to grow even more.
How do you know those economists were wrong? It's easy to conflate China's size with China's success. They liberalized their economy a great deal since the 1980s, which is responsible for the success they have had. That doesn't mean they couldn't be even more successful with further liberalization. Like a larger Taiwan.
