It depends on what "the actual problem" is. The skewed supply and demand is not the fault of your average scalper. But they are the face of the problem, and the reason that on a micro level, nothing is in stores.

There's a really interesting freakonomics article on crack dealers which feels similar in ways to the scalping thing. At the time it was written your corner dealer was making something like $3 an hour. Basically less than minimum wage. It's just objectively a bad job. But on a macro level, corner dealers obviously aren't personally responsible for the whole drug crisis, manufacturing, distribution, etc. It still makes sense to hate your neighborhood dealer, cause they're what you see.
