Dam good article.
I'm sure that if the French were to look at our melting pot that functioned quite well through the 1960s they might learn something. But ever since we adopted the Canadian model of multi-culturalism our immigrants have been increasingly congregating in their own balkinized ghettos. They may work but they are not becoming Americans.
Rather than worrying about whether the French are learning anything from us, I am much more worried about whether we are learning anything from them.
The real lesson is that Islam doesn't mix with any other culture including Western culture. Every country in the world that shares a border with a Muslim country or has a significant Muslim minority population suffers strife and violence and it is invariably caused by the Muslims.
The real lesson to be taken from this is that we had better keep the Muslims out or we will be in flames just like Paris. Oh wait a minute ... that already happened ... twice ...in 1993 and 2001.
