Governments, whether of corrupt police states or by-the-book democracies, are adept at not only deciding how their citizens should behave but also at exempting themselves from these same rules. Hong Kong is no exception. Most of the town is caught up in MPF fever.

MPF may be good for you, but for service providers and plan sponsors alike, the next few months will be grueling.
