On relation between hand-sanitizer and housing

People are out there hoarding hand sanitizer.

They’re driving the prices up because they’re buying all of it. Now they’re reselling it for higher and higher prices and making huge profits. Some of them are charging ridiculous prices just to let other people use it. So now there are people who can’t afford it even if some is available, because it costs so much. People are getting sick and dying because they don’t have any!

Oh wait. Did I say hand sanitizer? Housing. I meant housing. Damn autocorrect.
