Okay, you got me. The G&M, the conservative shill piece that it is, put out an article that leads the reader in a couple of circles to come around and ponders this thought...

What can be said about population growth is that it makes the costs of bad policy more apparent. If it means we are now beginning, at long last, to have a serious conversation about the barriers to investment and housing construction that have bedevilled this country for decades, then hallelujah for all those extra people, and let’s have lots more.

As you pointed out the article isn't blaming increased immigration. But it also isn't pointing fingers at property for profit. Instead the problem eludes to barriers to investment and housing construction.
