Annoying comments about housing posted on Hacker News:

I think they meant comparable (i.e. desirable, world-class) cities in the US. You want to compare London to cities like Los Angeles, New York, etc.
That wouldn't be a US situation, then, only a New York, or Los Angeles, or wherever situation. But it clearly says it is a US situation.
Why do you get to cherry-pick London only then?
Because the original comment that was replied to cherry-picked London and compared it to the US. Start from the top.
