distinguish between equal and equitable distribution …

Distribution of wealth and income is the way in which the wealth and income of a nation are divided among its population. Equal means 'same', whereas equitable means 'fairly'. That way, equal distribution means every individual gets a name share in country's national  income. Equitable distribution refers to a situation where differences in income are allowed but with certain limitations as such that these differences are socially warranted and are proportionate to the differences in qualifications and skills of different individuals in the society. 

A more equitable distribution of income may help accelerate growth and promote economic development. Equitable does not mean equal distribution of income. It refers to the distribution of income that is ‘fair,’ but the concept of ‘fair’ is subjective.
