Are they mutually exclusive?
My limited understanding of US History has led me to believe class played a prominent part in the creation of the US Constitution?
Well, I'm still not sure what you mean by 'class-based' dysfunction. We are, increasingly, legislating toward group rights and class-based privilege. Equal protection is widely disregarded and everybody gets a 'different deal', depending on how much influence they can exert over government. To me, that is, very fundamentally, a 'class-based' dysfunction. But I suspect you have something different in mind?
