You nailed my opinion.  I don't like assassination, but at the moment, I think it's the best option we've got.  We've tried voting and for 100 years our government has simply governed against the will of the people.  

As for American healthcare, we've got the worst of both worlds.  We enjoy the worst aspects of a private capitalist medical system, combined with the worst aspects of a government run socialist system.  It's completely broken and everyone knows it but nobody does anything about it because there are a few well connected people who make billions off the current situation.
