As soon as a government is created the people either become members of the ruling class or they become the subjects of the ruling class. The ruling class writes the laws and expects their subjects to obey. The laws written by the rulers always benefit the ruling class at the expense of working class.
Bigger is not necessarily better. A big government is like a cancerous tumor, the smaller it is the better it is.
The Constitution was written to limit the size of the government in order to prevent the abuse of power by unethical government officials.
Equality can not exist in a society where some of the people receive benefits and privileges which are not available to all. Without equality there can be no justice.
