Trump has always been of, for and by himself. That's the way he was, is and will be as far as I'm concerned.
Keeping his personality and track record in mind, and until I'm proven wrong by a track record that shows he is of, for and by the people, meaning ALL the people and not just for the select few of which the GOP has proven itself beyond doubt, I'm going to assume pursuant to his existing track record, that anything, ANYTHING Trump does is meant to benefit him and him alone.
So I'm also going to assume for now, that this Carrier deal that he's working on may or may not help some of the folks he promised he would take care of, but is primarily meant for show to keep the more fickle, skeptical supporters of his from revolting and to add some luster to his bluster.
The con man is still a con man no matter how he dresses himself, until he proves beyond doubt that those days are over. And that will take real positive results without hitches, loopholes and plausible deniability if things go south.
He has to earn a modicum of respectability with real tangible results. He has to fulfill the promises he made to the middle class and the poor. He has a GOP controlled House and Senate to work with, so there will be no obstructing going on as it was with Obama's administration. If things go wrong, the Repubs have no one to blame but themselves.
For now, all Trump is offering are words. Talk is cheap, especially coming from him.
