Politician turn out to be the most humble people on earth when they are looking for power. They make all source of fake promises to solicite the support of the people but when they succeed after election they will start to see themselves like God betraying all the people that sacrifice everything to ensure they are in power.
Politicians are suppose to replicate the humility they exhibit during campaign after winning election but instead they became so rude and arrogant to their supporters.
It is this dirty politics that takes its worst form these days, usually the most violent fights at polling booths. If you look then definitely look at the politics of low and developing countries most of the times MP ministers do the worst. They become most meek and gentle during polls but the people who live with them are mainly involved in bad deeds. By wearing a good mask they can get the right to vote from the people of the nation and only after getting the right to vote, they put on their real mask and start corrupting. They are becoming bigots by spoiling the rights of the poor and they have made a mountain of money in the country and abroad and made dirty politics.
One of the main causes of human conflict in the world is overstepping the boundaries of one's rights. When I interfere with the rights of others to ask for something extra then quarrels arise. People in the universe are naturally attracted to wealth and power, trying to take extra opportunities from their place. This does not mean that everyone is greedy, it is not unusual to have exceptions ie there are still many good and selfless people in the world. So if we all try to be aware and honest from each other's place maybe this filth among politicians will be reduced a lot. Sometimes we allow them to do dirty things in exchange for some favors.
