What I'm down with is everyone sacrificing a little bit of their individual accomplishments for the shared good... not with some people giving up their everything for people who'd never even think about their long-term responsibility to the community.
George Bailey's trip around the world should've been heavily taxed, sure, and when he was making good money as an architect in a big city, that too.
I'm all about the essential needs of the people (health care, education, transportation infrastructure, police and emergency services, defense, etc) being covered through the massive buying power of a nationalized single-payer system that no one can "opt" out of because it is a tax.
That is an entirely different animal than the bloody sacrifice of one man's dreams high on a mountain.
"We're all in this together, kid" from BRAZIL is a much better summing up of my ethos than...
George Bailey giving up everything for a bunch of people who would eventually squander that gift and never consider doing the same.
We don't NEED martyrs... hell, martyrs fuck the whole thing up because they trick people into thinking that that's all we need... the total sacrifices of a handful of great men and women and then everyone else can go on not worrying about it.
The sacrifices of George Baileys ultimately make the situation worse.
Everybody giving what they can, probably only a little bit but in great mass, means so much more actual lasting change than a knife through George Bailey's heart on the altar of America's God.
