They are cheap labor everywhere, the backbone of this country. When Latinos went on strike (illegal and legal) in Wisconsin to send a message to Walker every restaurant in Madison was shutdown and the farmers were panicking because nobody was there to milk the cows, and that's very bad for the cows.
The ideal result here would probably be to streamline the path to citizenship, make it significantly cheaper, and get these people paying taxes as soon as possible.
For anyone looking into the claim "When Latinos went on strike (illegal and legal) in Wisconsin to send a message to Walker every restaurant in Madison was shutdown", it appears to be a reference to "Day Without Latinos" last year in Madison on Thursday, February 18 (not to be confused with similar events this year).
Pretty much, most of the workers rights gains made by Cesar Chavez have been rolled back, hence why workers are forced to shit in the fields (due to a lack of places to do the needful), thus causing e coli and other outbreaks. Same thing has happened in the meat packing industry, worker protections have been gutted, and conditions there are similar to those described in The Jungle, a book which helped cause that industry to unionize and fight for safe & sanitary working conditions.
Up in Canada, they straight up import workers for low end jobs, hence why at Tim Hortons up north, you will rarely if ever see a native Canadian, its nearly entirely Asians, cause they are there on worker visas. The Canadian Govt has decided their workforce should be doing something better than making coffee or baking donuts, which isn't the worst idea when properly implemented.
