What are the implications of Donald Trump's mass deportation plan and immigration rhetoric for American society?

John Oliver argues that Trump's immigration policies would have severe moral and practical consequences for America. He emphasizes that immigrants actively contribute to building stronger communities and improving the country, countering the negative rhetoric with evidence of their positive economic and social impact. Oliver highlights that many Americans, including Republicans, actually prefer humane pathways to citizenship over harsh deportation measures. He concludes by urging voters to consider the human cost of these policies when making electoral choices, framing the election as a critical decision that will determine whether America continues to benefit from immigrant contributions or pursues destructive deportation policies.
