Americans will do it but you have to be willing to pay more then slave wages.
Here in Florida you can drive thru the rural areas and see the compounds the farming companies build for the illegal workers. Its pretty amazing how much those companies have gotten away with all these years.
As long as welfare continues to afford these people not to work, then of course. Human nature causes men to choose no work rather than produce a work ethic.
I worked for 50 cents an hour hauling used furniture around, cleaning out swimming pools, and shoveling horseshit(really).
Slave wages? No, as I had no other means to make an income and pay my way through college.
Using the term 'slave wages' to characterize what one is paid is racist, and fits the Alinsky mindset.
