That is the one thing that keeps you from moving to the US? Granted, it is a pretty big problem, but I'd say it is far from being the only thing the US gets wrong that the EU generally gets right.
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.
And I've been to middle-of-nowhere, USA and have family there so I know it's not a bed of roses, but you also don't fully realize how good you have it in many other ways.
