Indeed we have come to a state where each and every person is driven by his own interests and things like nationalism are used only if they serve our purposes! This is in stark contrasts to the countries in Europe where different countries have combined to make a single instiution (EU)! There is no point in blaming politicians alone for the mess. It's we, the people, who are not doing anything for the situation and simple living our lives! We give chance to politicians to come and rule over us while looking at the situation being dumb!
