Not quite.
Is it their fault they got hit by a MASSIVE earthquake? No.
It is their fault they have no economy, therefore, not money to build homes/building to safety code? No.
The issue isn’t with the Haitians directly, it is the fact that they have not had a stable government since the news first started being reported. There technically is no economy it Haiti, so they do what they have to do to get by. They have needed help for a long time, the Earthquake is what got them media coverage and opened the eyes of people willing to help.
