Can you quantify this? HK has one of the best welfare systems in the world.
If you're talking strictly social security, even the government acknowledges it has a problem.
Here's a recent SCMP article where the welfare dept itself states that at least 40% of HK residents in poverty aren't covered by welfare.

The good news is that the HK govt did, finally, just implement a standard poverty line (half median income). This is the first step and a long time in coming.
