I don't think it's so much that they really believe that their ideas are working in other countries as much as their arrogance makes them think that they can do a better job and make them work here.

It's the concept of a selfish altruism, because in their concepts of wealth re-distribution they get to receive the taxes and then pass them out. Any time you handle the money, you get to skim some off for yourself. It's no different than the multitude of 'charities' throughout the US that promise to feed all the poor children overseas, but you find the managers living luxuriously rich lives far beyond their ability to actually earn.

But taking weapons is a special kind of fear and arrogance. If they can take the weapons, they believe that the US individual will lose what gives them the power and personal esteem to stand up to them in their power. They truly fear people like Cinque in Conn. and believe that if they take his guns, that he wouldn't dare stand up and say NO.

Power attracts thugs.
Thugs in power strive to maintain that power.
Documents such as the U.S. Constitution stand in the way and therefore must be circumvented.
"Double-think" is merely a thug's way of deceiving his audience while doing anything he can to maintain and increase his power.
The deceptions used to be far more subtle.
In the past few years they have become much more blatant.
The time to "shrug" is rapidly approaching.

Along these lines, it seems there is a parallel discussion. Did the freedoms which enabled prosperity, thereby eliminate the challenges that press us to strive to succeed. Therefore the only ones of us that do are self-driven, a relatively rare skill, and one that don't are entitled to this that they didn't earn, just like they are entitled to the significant infrastructure that wasn't created by socialism.

Clearly not logical in their rationale. A=good for everybody. One size fits all. History is a great teacher, but only if one pays attention.
