By no means I am degrading my country. It's beautiful and I love it. But answering this question is very simple. I would like to outline the worst problem we have and for me that's the worst thing to have for any country. POPULATION. With populations comes poverty, pollution and illiteracy. There are very less jobs and flourished businesses. Government is corrupt. People get fooled easily.
