Governmet is a Political Tool. Politics means to look after the affairs of the people. Capitalism is failing, and Communism has failed, in respect of looking after the affairs of its people.
The only ideology capable of looking after the affairs of its people is Islam. The islamic Ideology, (currently not being implemented anywhere in the world) which is implemneted through the Islamic State, can act as a true 'melting pot.' It was implemented for over 1400 years and covered a major part of the globe. It is NOT a state for muslims only, rather it will and has looked after the affairs of people from other faiths, example Christains, Jews and Hindus.
Regarding it providing Happiness to it s people. Happiness is subjective; Micheal Jackson Maybe happy by sleping iwth young boys, Yorkshire Ripper maybe happy by killing prostitutes, and for Armin M, being a Cannibal may provide him with Happiness (

The purpose of the government is to look after the affairs of the entire populace, rather than individuals. Hence, laws,a nd regulations need to be set. The question here is, does Man legislate (given that he is prone to whims and desires), or are the laws based on devine text, whihch set general rules?
