I never said American citizens could replace all undocumented workers. I am arguing for an end to an immoral practice of taking advantage of a black market labor pool. In doing so wages would rise to a market rate that would tap a larger pool of legal labor willing to work at market rates. A one for one trade, no. That is not my argument. Having clarified that, could you clarify your position? Simply because such a large percentage of agricultural workers are undocumented, are you suggesting guest worker/ legal status and market wages isn't beneficial to society or the ag industry?
