This is what bears in Australia have been saying since the early 2000's when property prices started skyrocketing.

People starting selling their properties assuming it would crash.

It never crashed.

For the past 20 years I've heard people constantly claim "it just can't keep going up, the growth isn't sustainable, im NOT buying yet"

These people have been permanently priced out of ever owning a home.

Look at fucking graph, its had parabolic growth for 2 fucking decades LOL
