Because of the scrutiny involved in the melanin and testosterone of the workers on these projects, I think it is hard for illegals to work on these projects (as opposed to private work sites). The primary beneficiaries of these are the documented “victims” the benefit from affirmative action. When you see how much private sector union membership has shrunk in the past few decades, these jobs are among the exceptions (and probably the last holding on); these tokens are very expensive, and protected by law.
I will check the site later to see how many death threats I received. :)
