By American ideology I meant that everyone can become anything they want if only they work hard. Everyone can be a hero and defy their fate. Therefore if someone is in need, it's their fault for not working hard enough. If they don't have the money to afford medicine, then they don't deserve it, end of story.
And additionally, a gut-level fear of government and way too much trust in corporations.
The US would need different regulations. But the American ideology will probably not allow that.
