I find it strange when it's said in the US that universal healthcare is impossible when other countries have developed it. It's like if Russia had said after WWII that nuclear weapons are impossible and then proceeded to deny their existence. What takes the boggle to the next level is suggesting that greater gun control measures in the US are impossible when they actually were the law within my lifetime.
