Why the HDB $8,000 ceiling should not be raised

Just read an article giving the reasons why the HDB income ceiling should be raised. I'm now giving some reasons on why it should not be raised. Just 3 will do.

1. What does the recent Walk-In-Selection (WIS) fights tell you about the demand and supply of HDB flats?
2. What does the recent numbers of the balloting for both WIS and new flats, tell you about the demand and supply?
   
3. What does the growing number of complaints that they could not get a chance to own a HDB flat tell you about the demand and supply?

For those who keep track of these happenings, they will know the reasons why the HDB income ceiling of $8,000 should not be raised. Simply put... Supply is much lower than demand. It's not like those who earn more than $8,000 could get an HDB flat. I can think of much more reasons but I think these 3 suffice. Anyone who knows about economics know that pricing is all about demand and supply.

Sometimes, you have to think about those people who try year after year, but still unable to ballot for a flat.
