Now I have an honest question. Are businesspeople really this stupid and crooked? Do they really need someone to tell them, "Don't do this!"? Maybe the author was simply desperate for a topic and came up with this. We're in a sad state as a country if businessmen find these tactics tempting. Of course, if they have to be told not to do this, she may have to write follow-up columns such as, "How to Not Embezzle Company Funds" and "Sexual Harassment: It's Not a Good Idea".
When I have a case of writer's block next Winter, I can write a column suggest that it's a bad idea for baseball players to crush their arms under buildings, or how its not a good idea to make it your goal to get hit in the groin by the ball, and a follow up column on why Athletic Support cups are good for you.
