Of course the guy who says "x is a problem, let's do something about it" is going to benefit when people start listening. Your two examples are:
- Someone proposes and implements a free market solution - That asshole! He's trying to profit from this.
- someone proposes a government solution - Those assholes! They're putting people who believe it exists in charge of preventing it!
Just try to think about it the other way for a second. If this were a problem and you honestly wanted to do something about it, how would you do so, without it either making money, making you famous, making some other person famous, making some other person money, giving more control to some people, or taking control from others?
Once you can find a way to do it in a completely selfless manner that inconveniences no one, then you can complain about the conspiracies started by "alarmists".
