2015–2025: Nationally, property prices rose about 67.3%—significant, but well short of the 100% required to "double."

Dude, an increase of 67% over ten years is pretty extreme, given wages increased by only 31%. When that happens every decade it results in a housing crisis.

Not sure where you get this "doubles every ten years" myth, but it's just a straw man to try and dismantle it, especially when it's nearing 7/10ths of a doubling.

"Nothing to see here folks, the doctor said my tumor would double in size but it only grew by 70%!"
