Also, on the jobs thing, that is a really bizarre retort on the question of sacrifice.
Trump wouldn't have his "billion" dollars if those people hadn't done the work for him. It isn't a sacrifice to make money off of other people's labor. That's called the profit motive.
He sacrificed nothing to create those jobs. It isn't like he would've made more if he'd done the work himself. He took on risk - sure - for which he was handsomely rewarded when it worked, and for which he dodged responsibility when it didn't.
I don't begrudge him his money, but making it wasn't a sacrifice.
The real story, if Khan wants sacrifice, is that the candidate he's supporting didn't sacrifice either. If a good reason not to support Trump is that he's not sacrificed, then the same thing is true about Clinton. And the only reason we're not talking about that instead is that Trump wants to have his twitter wars.
