Why are the poorest countries always hit by such terrible natural disasters?

I watched them on the news this morning. Its sad, but I watched as they where handing out food and grown men were pushing their way to the front to receive food while ladies with babies in there hand were getting pushed to the back. There are lots of food and goods that hasn't been given out because of these guy. I think their hurting their selves and others while doing this, so i dont necessarily blame them for it but they should calm down and look at the big picture and there wouldn't be so much panic. I hope that everything gets better for all the people of Haiti and I think that they are going to have a bunch of help in recovering.
