Open Question to Healthcare Reform Supporters

Honest question:

If the inequality of the American healthcare system is so appalling, then why is it not even more appalling that those in third World countries have even worse healthcare?

After all, if there's a moral mandate to fix inequality, then it applies across international borders.  No American should receive any elective treatment until every human being in every country of the world receives the vital, lifesaving treatments that they need.

It seems to me that very few Americans who lobby for "universal healthcare" really mean that. What they really mean is "cheaper and better healthcare for me, for those I love, or for some nebulously defined 'underprivileged Americans'".

If we as a nation were really concerned about injustice, then we'd be doing something about the glaring global inequalities that are all around us.

Just an observation...
