One of the key pillars supporting social justice is that of fair wages. This is a question of seeing to it that workers are paid a fair wage for their labor. One may actually be inclined to argue that this is the main key towards the achievement of social justice. For the societies where workers are paid fair wages tend to have better social justice than the societies where workers are exploited.
You have to understand that in any given society, the ‘owners of capital’ tend to be few. Majority of the people are workers. Labor is the only factor of production they have for sale. So if we have a system that allows the employers to exploit the workers, you end up with lots of people who are desperately poor. And in such a setup, it is very hard to talk of any genuine social justice.
When you come to think of it, paying the workers fair wages is actually a good deal to everyone. For the payment of fair wages to the workers serves as a stimulus to the economy. The well-paid workers end up having more money to spend (that is, greater spending power). Let’s take an example of a worker who receives his paycheck through the Securitas paperlesstalx system. So he goes to securitasepay.com each fortnight, and finds a decent paycheck waiting for him. With time, this worker will get confident enough to start buying various expensive items: both the essentials and luxury items. Some of the money he spends in that process will go to the merchants who sell the various items. Some of the money will ultimately flow to the manufacturers of the various items. A bit of the money will flow to the government (through the various taxes). So it becomes clear that by paying the worker a fair wage, the entire economy gets stimulated.
Therefore, it becomes clear that, contrary to what some folks imagine, the pursuit of social justice (through the payment of fair wages to employees) is actually good economics.
