if the united states ever tried this, it would quickly adopt our health care model, because canada would provide the tipping point necessary for the united states to get to single payer. there is no abortion law in canada, and i would suggest that canada would provide the numbers necessary to pass federal legislation legalizing abortion in the united states. there's some other things that canadian voters would change about how the united states works and probably not much that the united states would change about canada or about being canadian. canada would benefit from more selective immigration, although i need to point out that canada doesn't have a porous border like the united states and the opposite would actually happen, as canada already has more selective immigration, but less aggressive enforcement. the best outcome would be to combine american enforcement with the canadian points system. ultimately, removing the problem of free market healthcare protected by the american border by removing it from the map would be a net asset for canadians, and i don't otherwise know why else most canadians would even give a fuck if we're americans or canadians.
i ultimately don't care about flags and anthems and hockey teams, although a us-canada hockey team would be unbeatable. i have no particular attachment to the word canada or the maple leaf and i don't care about maintaining stasis in global borders, which i think is naive and stupid. i am an advocate of the continuation of history; we're not done evolving or changing yet. we still have communism ahead of us in history, and then all the borders have to go. i would rather focus on changing the united states from the inside using democracy than on fighting some kind of stupid war against it.
