There was a time when every state had the right to secede. Of course, when 7 states did so over unfair taxation ( ie. they paid the taxes while other states received the benefits ), the federal government stepped all over those rights, performed an ingenious political motivation move, and we had our bloodiest war ever on our own soil. Supposedly, Texas in the only state to still retain this right, but seeing how state rights no longer matter in this country, they really can't exercise it (peacefully).
Secession probably won't happen, but many of the conditions are repeating themselves - the successful states being forced to pay for the unsuccessful states' poor choices & lifestyles ( check the voting maps, particularly rural vs city ). No matter which side you are on, you have to realize just how divided this country us right now.
