In 2013, Bernie Sanders gave the Washington Post an extensive interview on the issue of Guest Worker Visas. [‘This is a massive effort to attract cheap labor.’ Why Sen. Bernie Sanders is skeptical of guest workers., By Dylan Matthews, May 25, 2013 ] I do not understand why Sanders thinks corporations need low cost visas to displace US tech workers or agricultural workers, but his rhetoric on this issues is more focused on working conditions for US workers than many other candidates.
