Insane differences: if you've got a chronic condition in the States, the prime rate will go up on that if not an outright refusal to insure it. In Europe it's the other way around; a chronic condition could qualify for free coverage.
Now as far as political discussions went, not many were impressed by Obama's reform because it apparently didn't go far enough. I don't know enough about it to form an opinion. Others on the contrary pulled off some spiel about loafers and commies. It must be that manifest destiny clause. I personally have no time or energy to waste with anyone bent on defending a system that's iniquitous and degrading. But an important issue is terminology. What's lambasted as state assistance is simply an inalienable right.
On a personal note I trust you also have positive reasons to go abroad.
