McDonald's is Unethical

I noticed this morning, as I was waiting in line for my daily Egg McMuffin, there was a sign up saying you could win a trip to Disneyland just by buying a Happy Meal.

How is this different than gambling? And doesn't this promote gambling to children?

Of course, I also have a Diet Pepsi sitting here on my desk with a promotion on it where I can win an XBox360. Probably fewer kids drink Diet Pepsi, but the promotion is not limited to just Pepsi's diet drinks. Again, this seems like gambling.

I guess the difference is that you spend money and you actually get something back. Whereas with real gambling, you get nothing back unless you win. Personally, I think I should be able to gamble if I want to, but I have a problem with corporations targeting children.
