I'm not trying to convince you that my way of thinking is correct, only express my alternate view.
Example: unknowning buyer walks into a car dealership and wants to buy a car. Car salesman seizes opportunity and charges more than car is worth.
See, I have an issue with that. Taking advantage of someone's ignorance at some level just doesn't sit well with me and strikes me as pretty close to dishonesty. If that doesn't bug you, so be it, just be prepared to reap what you sow.
