What the collapse of the Ming Dynasty can tell us about American decline

Ming China was by far the greatest nation on the planet for most of the 15th and 16th centuries. It was certainly the biggest and the richest. Ming technology was in advance of anything in Europe or the Middle East, with movable type, compartmentalized ship hulls, steering rudders, advanced farming techniques, and the ability to solve systems of linear equations. Ming military power conquered Mongolia, subdued Korea and Vietnam, fended off a major invasion from Japan, and quickly disposed of meddlesome raiders from Portugal and the Netherlands. Taxes were low, industry was strong, and the society was peaceful and stable.
