No, Grisu and that is not why the South Seceded. Nice try. I guess when you can't beat someone's argument the next best thing is to try and classify them as a racist.
I beat your arguments already at multiple occasions; you are just the only one who does not realize it.
No it does not assume equal bargaining power, again you are making incorrect assumptions. Bargaining power only exists of these is a shortage of labor which in the case of field pickers there really isn't.
So you admit there is no equal bargaining power which means there is no free market. A market can only be free when both sides have equal ability to walk away from a deal. If one side needs to accept any wage in order to not starve we are not talking about a free market anymore. A person who can let an apartment stay empty for months has a different bargaining power than someone who needs a place to live.
Anyway, way off from the original topic.
