Is Wealth Distribution Today Just? In current times we often observe that many members of our society receive less than other members regardless of whether they are no less deserving. In contrast‚ there are some who have ownership over assets and earn income that they may not be deserving of. The distributive balance is upset and wealth distribution today can thus be seen as a social injustice. This injustice that is becoming more noticeable as people start to become aware of the facts‚ as we can
