From the little I have read with regard to the Mixed and Free Market economy, I have come to realise that both systems are very good depending on the environment they are practised.(posted 6981 days ago)Government exists to identify the needs and wants of its people and create a condusive atmosphere in meeting those needs and wants.
The people also owe a duty of making sure that their social obligations are carried out in a manner that realise the dreams of the government in promoting the social and economic life of the people in a given country.
Government is just a small body deciding for the whole country, which at times does not help other people as needs and wants of individuals are not the same. There is the need to bring the private sector into the economic problem solving equation.
Because of human selfishness, free market economic would tend to marginalise the very poor in the given society, since it is operated on Laissez Faire approach, that is 'let alone'. So many market abuses, such as monopolic power that requires government involvement in correcting these abuses to make life smooth for each and everyone.
In the nutshell, mixed economy is the best system to accelerate economic growth and development .
