One of the hallmarks of a narcissist is the way they have undying faith in their own capabilities regardless of reality. When Tty foams at the mouth, he really thinks he is offering a solution. Stagnant middle class? Make the top marginal tax rate 99%. Problem solved! Want universal healthcare? Ok, its free to everyone! Problem solved. Higher education costs too much? Boom, its free. Problem solved! They truly see this as a solution using the same type of fuzzy "logic" that the right does. Got a deficit? Cut taxes. Problem solved, the additional growth will cause increased revenue (despite every other time in history when it hasn't)!
Narcissists hold their most virulent hatred for those that share the same goals but fail to see the benefits of their half-baked plans. This is because their top priority, above all else, is to make themselves seem smart, important and relevant. If somebody else has a different plan for achieving the same thing, they threaten the narcissist's ego. Those people are the real enemy, not the ones who don't share their goals in the first place.
These people would rather set fire to the house than fix the roof in any way other than the one they think is right.
