Exploitation, or at least Government sanctioned exploitation, would not exist in a libertarian society - maybe that's the solution. Politicians and government bureaucrats usually forget that their laws and regulations affect real, live human beings.
Libertarians treat each individual as unique, with great potential.
We favor a system which encourages all of us to discover the best within ourselves and make the most of it. A system which encourages the development of the most harmonious relationships among all people. If so, then it's proper to call on government to help the victim against the wrongdoer. But, if not, the government should not get involved. In most instances, people are better off if allowed to work out their own problems through voluntary cooperation without introducing the coercive tool of government.
