You need to compare it to population growth, decades of building backlog, job growth, etc.
I was just pointing out the the linked post shows how NYC construction is stagnant, not "active". It was unclear if he meant "active" as in "they're building a large quantity" or as in "currently happening".
Foreign money or no, if you have a very desirable city with a growing job market and stagnant construction, prices will appreciate. I would challenge you to find a single counterexample
Foreign money doesn't help prices but it's more a symptom of our problems than a cause.
Also, NYC population is not declining. I wish. There have been some stagnant years but nowhere near enough to compensate for 50 years of underbuilding.
