This is quite interesting and indeed it is, because those who are uneducated will never protest what they receive, either in the system or others, so that people who are above or people who have power or authority can easily fool them.
It is common knowledge that someone looks like money to those who are above. I might take a small example, where someone can easily be bribed with a small amount, even though they will suffer for life. While those who bribe, they will enjoy it by taking advantage of their power.
It is not even about uneducated people, as in people who didn't go to school. It is about uneducated people, in the sense of people who do not follow the money trail and see how they are paid lesser than what they are worth, by a large margin. Companies has always been using blackmail to make more profit, and that will continue to be the case unless all of nations get together and stop them, which will not happen.
You could always use any nation as example, like take USA for example, charge all these rich companies more tax, and request them to pay higher bottom salaries, to make sure that everyone gets a fair share, but then they will just either stop doing what they do, or they will just move their company somewhere else, so you won't really get what you should.
