Political infighting can pull down economic growth. This is true everywhere in the world.
In 2011 in the US we see the national debt ceiling brinkmanship in Congress pull down consumer confidence and business hiring. In Europe the dispute between German and southern countries - Spain and Italy - can pull the entire euro zone into recession. The same force slowed down the economic development in Africa, India, and many other places in the world.
Strike and labor dispute is another example.
To foster growth and prosperity it is important to resolve political differences.
