I am pretty sure that the Americans would not do that work anymore. First off it require a bunch of them to leave cities and there is a remarkable tendency for people not to do that. Second, the work is extremely grueling. Many Americans are no longer able to do that sort of physical labor. Finally, the spiraling cost of food would be so inflationary that we could not afford to pay the people doing the back breaking labor enough for them to consider it worthwhile compared to their other money making options.
