I hate the Expoltation of labor, when someone treat their workers unfairly for their own benefit.
That is unfair in the society and the government are not doing anything about it
Yes it happens because of the fundamental asymetry of power in the relationship between workers and employees
What do you think are the solutions to such evil acts
Well I am not sure, but I don't agree with Marx's explotation theory
What did Marx's explotation theory says?
He explicity rejects the moral framing characteristic of explotation, I don't think that is fair.
Does this mean he supports the exploitation 
No, just that he restrict the concept to the field of labour relations.
