Renowned for its high concentration of Rolls-Royces, expensive real estate, and posh shops, the Chinese special administrative region has plenty of rich who enjoy showing off their wealth. However, Hong Kong also has one of the largest public housing sectors in the world, with about half the population living in government-supported or -subsidized housing estates. The city has no minimum wage—except for domestic helpers from the Philippines, Indonesia, and other countries.
