This world is made up of people, of which those people that band together so as to create a particular construct in which they base their business enterprise primarily upon the profit so to be made by their products so to be sold; and thereby they make it their point to take advantage of or to exploit those that labor upon that product, as well as to make a conscious business decision to practice the manipulation of susceptible people to encourage the purchasing of such a product, have quite obviously made the determination that for them, the making of profit, and thereby the benefits of having that profit, outweigh whatever concerns they might have to the fairness and value of other people's basic human rights.
First, the nature of a given business enterprise doesn't have to be conducted that way. If more businesses and the people that make up those business enterprises made it their point of principle to pay a fair salary for a fair day's work, and to price their products to sell at a fair price, then this foundation would in concept, provide the necessary means to sustain and to grow those enterprises, day-by-day, along with the fact that those so employed there would at a minimum, be earning a living wage. A mindset such as that should be the primary objective of every respectable business enterprise, so created, of which, those that lose sight of the humanity that we share in common with one another, to replace such with the exploitation and the greed to thereby take advantage of situations that favor those with money, power, connections, cleverness, and the like, have decisively decided to take the low road at the expense of doing the right thing for those that they work and associate with.
In order to try to make a living, people have to work, and in a world in which a lot of those jobs so being offered, necessitate working for a business enterprise, those that are the common laborers to such, often do not have the skill set or the wherewithal to dictate the terms of that employment. Rather, in many cases, that of which these subject employees will get paid, is determined by that business enterprise, irrespective of the need of the person so seeking employment, the fairness of it, or even a decent consideration as to whether the salary so being agreed to represents a living wage.
Those that believe that the free enterprise capitalistic system is the best economic system the world has ever seen, are typically those that sit comfortably on the winner's side of such a belief; for in reality, when it comes to any economic system of which profits, more than anything, rule the roost, one can expect, that the unyielding lust for profits will lead to all sorts of ill consequences, such as lying and deceit of all stripes, pollution, unfairness, exploitation, manipulation, injustice, and a massive disparity between those few that have it all as compared to a significant part of the population which pretty much has nothing.
It isn't that the capitalistic system is wrong; it is just that there needs to be proper governance exerted by a robust government that regulates such in a manner in which primarily people are held at a higher value and thereby of more importance than the mere making of money.
