Whether they're separated by comma or period doesn't matter. If him saying that he's worked hard, built stuff, created jobs, were NOT intended as examples of sacrifices, then why utter them right after claiming he did too sacrifice in his life? And of course if he said, "I have sacrificed. I spent 6 months without pay rebuilding houses in the third world for poor people" every single reader on the planet connects those two as related sentences, that the speaker intended his time rebuilding houses without pay as an EXAMPLE of his sacrifice.
No, borrowing tons of money and hiring others to build Trump-branded properties that Trump intends as profit making ventures aren't sacrifices by any accepted definition of the word, but Trump believed they were good examples.
And your second excuse is also nonsense, or ****ing stupid, to use your terms. All that means is you get to choose how to interpret any two sentences uttered by Trump. If it makes Dear Leader look good to connect them as common sense and a literate reading would demand, you'll do that. If it makes Dear Leader look bad, then we must of course consider them unrelated!
