We already do this and I would argue it is good. We allow anyone to enter any hospital emergency room in these 50 states to get treated. I dont think we should be turning anyone away from an emergency room. That is healthcare.
Why doesn't what the Pope said concern any of the other nations besides the US as well?
"We allow". You mean the "Gov't allows"...right? Those aren't free choices by hospitals.
The Pope is not just addressing the US. He's addressing income inequality everywhere. But he knocks "trickle down" which is a buzz phrase for free markets and Reaganism. And the statements about Gov't policy for the "common good" are typical of those given by leftists, not capitalists.
