Pack Mentality and the Euro

Britain, Sweden and Czechoslovakia have decided the Euro agreement is not a good one for their countries.

Perhaps we ought to be paying more attention to those countries who take the divided path? Those countries, civilizations or individuals who forge the untraveled road are often those with vision. What a quandary we live in! Group consensus leading to extinction or learning to ask the unspoken questions aloud and accept the consequences from the lemmings??
