It's weird the way some people will rationalize being an asshole. I guess "talking" someone into something ( i.e: lying, manipulating, misrepresenting) is always justifiable, and the only blame that can be attached is to the victim. Too bad the law in pretty much every developped country disagrees with your retarded social darwinian point of view.
Good job teaching the 9 year old to never trust anyone though, not even his own brother. And of course teaching the 12 year old that anyone dumb enough or lacking enough information to be manipulated is fair game. That's definetely not the type of people who will afterwards chuck you in a home if you ever turn old, senile and incapable of taking care of yourself, no sir (throwing some selfish considerations in there, since that seems to be one of the things you value).
I can very well support the argument that a robbery took place. There's been one person in the thread who mentioned the legal term of "misreprensentation". I suggest you read into it somewhat. I'm not making it a moral crusade over the evils of capitalism, personally. More the evils of cunt-like assholes who believe their douchebaggery is perfectly natural, and use capitalism as a smokescreen to justify it. Despite what some people believe, capitalism =/= social darwinism.
