For thousands of years, there was a clear explanation for social injustice. German philosopher Georg Wilhelm Friedrich Hegel called it “master and servant” — one has the power and the other must obey.
But with the end of feudalism and the emergence of capitalism, this power relationship faded into the background.
Now, workers can make contracts with companies – or not.
But economic inequality didn’t create any other choice than to “freely” choose to become a servant. At the same time, this inequality was reproduced, because workers had to cede added value to their employers.
