In my opinion, in modern civilization, concentration in megacities is inevitable. I think it is unavoidable whether it is a centralized country (France, Korea, etc.) or a decentralized country (USA, Japan, Germany, etc.). Since the benefits of globalization are concentrated in cities, the high-skilled workforce tends to stay in big cities. As in the example above, poor quality of care in rural areas is just one consequence. (In Korea, where I live, this issue has recently been on the rise.)
