I think the tax policies in state's like CT (and their failure to reign in the cost of public collective bargaining agreements) has more to do with migration from high-tax states than "the Trump tax plan." The cap on state income and property taxes seriously pre-dates Trump for instance -- it was a cornerstone of Romney's tax plan during his campaign and I can trace it back to at least McCain's tax plan that was offered as an alternative to Bush's more expensive deal that was adopted. I supported it then and I do now, although I will be personally harmed by it, because I believe it is good for the country.
I won't try to sanction Trump's narcissism and juvenitis, but the rest of the conspiratorial stuff strikes me as more of the hysteria that is prevalent right now surrounding everything Trump. Policy-wise, pretty unfounded but very good for the ratings (and eventual pocket books) of the Java Joe in the Morning crowd.
As I said earlier I would have preferred paying for much of the recent tax bill with the proposed border adjustment tax, but it occurs to me now that based on your post many would have interpretted that to be part of a divisive attempt by the Republicans to pit "the makers against the takers" too. Unfortunate.
Reading the last half of your post reminds me of something Bush 43 said in Dallas a couple years ago. Too often we judge other groups by their worst examples while judging ourselves by our best intentions. And this has strained our bonds of understanding and common purpose. We can't blame Putin for that.
