That's actually the whole problem of too much subsidy into a government scheme.. that people will do all kinds of things to abuse it.. In sgp, the housing is subsidized but by alot lessor than in hk... its affordable but we are still talking about ordinary couples needing to stretch their loans 30 years to make a comfortable living. Still, we have heard of people trying to 'separate' legally so they can acquire a second house unit.. etc.
