240 years ago, a group of rebels agreed to declare political independence from my ancestral homeland. Political and economic issues drove the decision, immigration, taxation, free trade, self governance. There is a famous quote about needing to rise together, or all hang together - being a thinly veiled reference to being strung up by their necks if the revolution failed.
Would any of us be so bold today? Would you risk your life for a political or economic issue? We have a hard enough time getting people to vote on election day.
