This is The Thing. The list is much longer. On the other hand there are many problems that are worse here as well. But for me the main thing is that in US people are dying or lose everything just because someone in the family got sick. This is sick!
It seems doubtful this family man would move to the US and immediately become a homeless, mentally ill victim of police violence.
Everyone agrees the US has plenty of issues (and there's plenty of homeless in Europe too), but you're replying to someone mentioning his personal reasons and telling him a laundry list of other issues that America has.
