Thanks for the well-researched article.
The question is not whether illegal [sic] immigrants should be allowed to work in the U.S. People are already working undocumented. The question is whether they should continue to be exploited based on their undocumented status.
Using "documented" and "illegal" to exploit workers and bring down everyone's wages has long been the practice here, especially in California. See my article on the "undocumented" Native Californians:
Other countries also use "documentation" to exploit. China does this internally, by requiring documents to work outside of your immediate province. There are over a hundred million in China working without documents, and thus without any legal protections, for abysmal wages and working conditions. The devices we are now using were probably made with such labor in China.
The answer is to stop dividing workers by documentation, immigration, race, or any other basis.
