Yes they do. But we -- that is, our nominally democratic government, a "power structure" which you have arbitrarily equated with a collection of private corporations -- have placed restrictions on immigration, and some light restrictions on foreign ownership of real estate itself, for precisely this reason.

Secondly, Canada, whose real estate markets have been even more seriously disrupted by authoritarian regimes across the Pacific Ocean, have already placed outright, albeit temporary, bans on citizens of those regimes from parking their capital in the domestic real estate market.

Your characterization of my argument is specious and straw-man-esque. You are assuming that globalization is a given, that borders are always porous, that neoliberalism is the only way of looking at the world. I am kindly inviting you to reconsider your point of view, in light of evidence that it has made housing more unaffordable for the many Americans, disrupted their livelihoods, and dissolved their communities.

Or you can keep making colorless jokes to yourself about the property markets on Mars, up to you.
