No, it doesn't. It's not really fair to make a blanket statement like that. The "evil" that you describe, if you will, can be said of any profession that relies on sales in one way or another (which is probably most of them, even for salaried employees, since no sales means no job and no salary). It comes down to the individual. Some people will do the very best job that they can... and some won't. That's life. Just the way it is. Of course, the same goes for people who aren't paid, as well.
