I agree. I don't begrudge any man his profit. And yes, scalping is an illegal activity, and by definition of the law we can't call it a just profit.

At the same time the scalper, like businessmen, incur costs and risks (buying game tickets from fans on game days and the risk of arrest and prosecution). They work hard to get tickets and sell them in the course of a couple of hours, working buyers and sellers. It's a skill, involving direct and persuasive communication while realizing the market demands for the tickets. Those crooks really work hard for the money.
