Ah, the old misguided belief that people are tricked into buying things they do not want or need as opposed to the reality that companies make things because people want them. Volvo markets cars that are somewhat higher priced because of their alleged superior safety features. John Browning came up with a design that had a unique safety feature that was not mandated by the govenment and has done pretty well in the market place at a higher price partially because of that feature (sold by a corporation). As to other safety features, most exist because the various industries develop voluntary standards (ever hear of ANSI? UL?) and provide many products with a choice of safety devices in their product line to meet consumer demand. There it is, the demand word. Part of supply and demand, the basis of our economy.
3. Seriously? If many corporations had their way they wouldn't spend a nickle on anything that didn't generate profit. I'm not saying they're "evil" but, by nature, they are geared to make as much as they CAN...regardless of consequences. We'd have unsafe products everywhere because safety features cost money. They'd also have enough money to put on a media campaign to brainwash the less intelligent. Have you ever watched a commercial and thought "Well that's the dumbest thing I've ever seen"? That commercial is there because it WORKS. For every intelligent person that sees through the dumb stuff, there are thousands that do things "because I saw it on the TV".
