Kind of. That's just supply and demand. But markets are never perfectly efficient. From my personal experience working in an industry that hires a lot of minimum wage workers, I encounter a lot of people who just don't realize that they could make more doing something else. I mean, they understand in some nebulous way that higher paying jobs exist, but not in an actionable way. With more information, they might notice that they could squeeze out a particular guy making $30 by doing the job for $25 per hour. But they don't even go there because they lack the information needed. At the same time, those minimum wage jobs I speak of aren't going to pay more if the people leave – the work would just disappear. So while these individuals would make more, they would place downward pressure on the overall market in making such a move. By keeping the information hard to come by, however, you can avoid some of that competitive pressure.
