Social justice means that people have a right to live in dignity (see Maslow's Theory). A democratic nation which operates through both free market capitalist ventures and government safeguards (subsidies, government salaried, regulations, incentives, bailouts, etc. - which is essentially money which comes from the taxation of its citizenry or foreign investments) is consistent with its value system, its essence of moral responsibility for its people. It's not only caring for the richest, smartest, most educated, better-looking of the population - as repeatedly reminded in our Jewish scriptures and tradition of no one being left behind. To ignore that underprivileged sector of the population as they struggle year after year with employment, health matters or housing, can certainly be another individual's prerogative, but not in the daily business of government. It's not a sociopolitical ideology issue but rather one of value system where no one individual should be left behind.
