Japan is a good example that Keynesian fiscal policies work. Sectoral and other questions Japan plays an important and constructive role in the structure of security and trade in the Pacific. Cartels in Japan should not be a concern of US policymakers. It's after all the Japanese who pay the cost of such policies via high prices that lower their welfare, not ours. Structural reform is practical, and would rapidly improve the livelihood and real income of the average Japanese, with few macroeconomic side-effects.
Japan is the engine of growth for Asia, and if it stalls, recovery elsewhere is inevitably hampered.
