Answer:
Wealth distribution is used to compare the wealth of members of society. It shows the economic state of society. It is different from income distribution because the basis of calculating economic inequality is based on the ownership of assets(Lands, Factories etc).The income distribution is calculated from the current income of members.
If the assets and wealth are concentrated in the hands of a few people then it gives rise to inequality. Historians like Karl Marx has termed the people who own the assets, wealth and means of production(Factories) as Bourgeoisie.
