A Utopian fantasy based on the Leninist concept of "equality of outcome." It says that since you have more, it must be taken away from you to give to those who have less, so that you are both equal. So there is much in common with the petty thief , who steals your wallet at gun point in order to equalize both of your wealth. Though this never seems to apply to rulers, who always seem to be exempt from social justice policies.In order for social justice to exist, there has to be a ruling class to mete out that social justice. If there is an elite ruling class, then there is no social justice. So the concept of social justice always collapses in upon itself. Social Justice is generally supported by hipsters of all ages who can't afford weekly groceries or gas for their cars, but who are simultaneously bedazzled with hundreds and sometimes thousands of dollars of tattoos and piercings.It is often used by power hungry despots to fool voters into surrendering their rights and liberties in exchange for promises of free stuff, while lining the pockets of the ruling class with the stolen wealth of the people.
