It's easy to act like a hero behind a keyboard, when confronted to the prospect of having to choose between our life and the life of a stranger in another country, the vast, vast majority will sacrifice the stranger and if I had to bet on it I would bet you would do the same because the odds would be in my favor. Heck, it's a choice we make every day by purchasing crap made in third world country instead of spending more on stuff made locally, including whatever device you're typing on.
