Watched it, got the joke, hated it.
I understand here. They're trying to show as the douchbag that always wins. Kind of the opposite of the southpark "You know what? I learned something today."
The problem is that there is nothing for the audience to root for. The good people are treated like crap, and the douches always win. While that might be true in real life, no one wants to watch that on TV. Cartman and the gang on "It's always sunny" are jerks, but they get what is coming to them. Stewie Griffen while not nice would either inadvertently fix the problems of others or when he is pure evil at least just break even and no one really got hurt. Here there is none of that. So it comes as "Why would the audience care about this?".
Sometimes, Just Sometimes, the joke's on you.
