It is not fair to private homeowners in HK. During the mortgage period, they need to pay interests to banks or even to the designated banks, property insurances to insurers/banks, management fees, maintenance expenses, real estates agencies charges, property tax, government rates & rent, together with many uncertainties in the market. Actually, they are real contributors to the local society.
In a normal and an advanced community, nobody loves to see the governement to cap the prices of the utilities, such as electric, water, telecommunication, and gas bills. Of course, the wages of individuals & local investments should not be fixed.
