I think the Koch brothers are essentially traitors who don't believe in representative government and are waging an active campaign of sabotage against it.
Not so much as traitors, more like "above the law." They want the representation in the government to be of money, not one person one vote; for them it's one dollar - one vote; so they have a lot of representation at stake. And they are using their wealth to accomplish this, in a lot of shady, but currently legal ways.
There is a reason why money needs to be removed from politics, same as religion and the state need to be separated.
I would have to say that I do not know them, but I dislike their politics. Of course, if I had their money, then I would probably like their politics.
The Koch Brothers use and manipulate the system to get as much influence and make as much money as possible - legally.
If you agree with their political goals, then you like them. If you don't agree with their political goals, you dislike them.
The biggest problem is, no one but the brothers themselves really know what their ultimate goals are.
I dislike the Koch's blatant abuse of the American political system to their own gain and to the detriment of the citizenry of this country.
That said, it's not surprising in the least that the wealthy elite control and hide behind whatever passes as the highest form of government in the land (this is true even from pharaoh's time and most likely before), it's just irritating as a member of the group being screwed over that they are so out in the open about it.
Maybe they're not out in the open. Maybe they don't fear any reprisal whatsoever because maybe they have insider knowledge that nothing will change and that their's is the new paradigm for government in America.
May I present to you commoners the new lords and ladies of the realm of America.
You may bow and pay homage... or even MORE homage than you're already paying.
