I had great-grandparents who worked for the company store.. i.e., slave wages (From the age of 9 qne 10 years). You work for just enough to pay for the mattress you sleep on and the bit of food you need to sustain yourself. In any sense of human compassion it is recognized as 'slave wages'. (Basic subsistence - if you're lucky). I despise people who prey on the poverty and ignorance of others. Nevermind the harm they do to the American middle class by lowering the quality of life to a third world standard.
Of course I would hope that you would NOT do that, after all you were quite concerned that we taxpayers and churches subsidize the necessities of the illegal workers. You just don't seem to be too concerned about the obligations of their employers.
