You will consider this a threat. You should. You're killing us right now. There's nothing just about it. It's just power, ego & greed. You should suffer the same callous fate that you are exacting upon us. F*ck you! Let that sink in, f*ck you. We're moving towards your outlook, just towards you.
As this shut down continues, more Luigis. You could not have a bigger example of the rich leveraging their power to show that they don't give a f*ck if you die. Why should they be immune? Be a god d*amn human or f*cking die already. It never should have come to this. But, this is your greed.

Wake up call. "Illegal immigrants" aren't taking your jobs. Trump doesn't produce anything in the USA because it's cheaper to get bullied labor from other authoritarian regimes. Stop buying their con that immigrants are your problems for work. It's the fascists that screwed you, not immigrants.
