In fact, Trump's stated position on women, blacks, Mexicans and Muslims is that he loves them. To my knowledge, he has never said anything derogatory about women in general (only specific women he didn't get along with), and what has been framed as anti-black statements were in fact criticisms of Democrats for failing the black community. His stated policies regarding Muslims are directed against terrorists, not Muslims in general; just as his policy regarding Mexicans is directed at illegal immigration, not Mexicans or Mexican immigrants in general.
Contrast that with Hitler, whose policies regarding Jews, Gypsies, and other "mud peoples" (what a dick that guy was), were always directed against the whole. Who never said anything nice about those groups or walked back a statement about them. There is no comparison between Trump and Hitler. The breadth and scope of the National Socialist agenda would blow your mind. Trump has a platform of economic nationalism. Hitler intended to completely and fundamentally reshape humanity and reality itself. To compare them is madness.
How the hell does that work?
Live in a State that mandates a silly low alcohol content for your beer? Drop in the catalyst, hook it to a battery and voila! Problem solved.
You're also assuming that, unlike the rest of human history, there won't be some new need or endeavour that arises to demand labor.
Why won't sharks eat lawyers? Professional courtesy.
