Whose fault? Simple,...theirs. Their choices, their religion, their beliefs, their philosophies, their leaders, their choices, their votes (or lack of), their govenments, etc., etc.,etc.
With the exception of people who have fatal, incurable diseases, people locked up in prisons, people physically restrained under the thumb and gun of and mined and electric fences, physically restrained, people everywhere have choices. They can vote with their feet. They can leave. They can walk, swim, fly, hot air balloon, boat or raft to another place if they really want to. It might not be easy, it might be dangerous or life threatening, but they can do it if they choose. They might die trying or die at the hands of their oppressors, but almost everything in life is 50/50.
You are either alive or dead. You can die there oppressed or you can die here or someplace else free, either in comfort or modest circumstances but at least more free. You can take a chance and perhaps prosper in a free society or sit around and blame the big bad West for your misery.
On a personal level, I've learned that generally, no one, no one else is responsible or to blame for any of my "problems". I've done this, including many stupid mistakes, all by myself. I can always leave or vote with my feet. It might not be easy, it might be tough, but almost everything in my life as a free American is my own choice (with the exception of random violence, acts of Mother Nature or my own stupidity, lack of thinking or prescience or just plain bad luck. Blaming someone else or something for your bad luck or circumstances is mostly baloney. We're all adults here, think before you operate your mouth and blame America.
Want some cheese with that whine?
Of course, this is just all my opinion, I could be all wrong. But then I am a smart, happy, handsome billionaire with a large penis and a fast luxury automobile and a great big house, so I could be right too.
