There is some contestation regarding whether law is mostly about justice and fairness (and equality) or whether it's mostly about efficiency. The idea of efficiency doesn't seem to be extremely honourable, being connected as it is with capitalist markets and correlated associations such as greed, selfishness, and, worst of all, great wealth. This explains why lawyers value morality and human kindness above everything else. In Canada, where everybody is good and upholds the correct moral values, they're actually forcing lawyers to sign a blood oath promising to be good and kind and show equal love to everyone. Soon other countries will be following that illustrious example.
Is “equality” an essential component of justice? We know that justice is a good thing (nobody would argue that injustice is a great goal to aspire to) but does it follow logically that the full force of the law should be harnessed to equalize everything? Equal amounts of stuff, equal pay for all working people especially if they're women, equal benefits for all unworking people and equal opportunities for all to have an equally good life. Everything should be equally distributed. Because otherwise it’s not fair. More importantly, it’s unjust.
