If everyone wanted a different society there would be chaos. It is already happening in areas where you throw hoards of different cultures together. The social contract means we agree to abide by certain laws and norms.
I would argue that society is already chaotic, and this is because of conformity. And I wasn't talking about the problems multiculturalism brings but this is a great example. Multi-culturalism is accepted without question by the conformists who just willingly go along with it. To any free thinker there are obvious problems with multi-culturalism, but due to such societies raising their citizens to be conformists, they are unable or incapable of speaking against it. Society could obviously be made far better if people rebelled against multi-culturalism, reformed it and came up with more workable solutions for the betterment of the Nation, but conformity prevents this. The same goes with many societal issues like ridiculous drug laws, anti-euthanasia, capitalist corporate profit over civilians well being etc etc.....
The problem arises when the laws and norms are dysfunctional, as they quite often are. For example, in the Country I live we have laws preventing an individual from criticising someone based on their religion or race, you can be charged for criticising Islam and even multiculturalism, several Journalists already have. Now, if you are a conformist, you just go along with that and say and do nothing, but if you value freedom and justice you will rebel and speak out,even at your own peril. This is how progress is made. Conformity is how evil ideologies like NAZISM got such a foothold, same deal with ISLAM.
