It gives rise to the other question, and yes—this crowd is white, white, white. If you see a black person here, at all, they are probably a panelist. This is a crowd that is certain that racism is dead, or at least dead enough, a few thousand white people praising their own modern outlook on things while a staff comprised almost entirely of black and Latino members.
Trump's speech starts with a collection of generic deficit talk, which gets mostly perfunctory applause. He makes the case for more immigration from Europe, saying that after we educate these people, after they go to Harvard and other schools, "we throw them out of the country." Then Trump notes that Newt Gingrich offered him up to perhaps pay for the White House tours for the rest of the year, saying he's up for it. The rest of the speech, in fact, is about Donald Trump, the things Donald Trump has done and is currently doing, and how America should do things more like Donald Trump. He says we should take Iraqi oil in proportion to the costs of the war. "What the hell are we thinking?" he says of the decision not to. He says we should pay a million dollars to each deceased service members families, because even to the deficit hawk, that is "nothing". He says of protecting South Korea, monetarily, "we get nothing." It is all about the greenbacks. The whole speech. He says the OPEC members "I know them, they're all friends of mine."
He gets a brief ovation, and everyone gets on with their lives. Or to Mitch McConnell, which isn't quite the same thing.
