I think Trump may have untreated ADD, and also I suspect NPD.
Neither would necessarily stand in the way of his being smart in certain ways (although I don't think he's smart, so much as been lucky to have been born into wealth) but especially the NPD would be problematic because NPD people lack a moral compass and also often make incredibly bad decisions.
The late Joanna Ashmun has a
very good site on NPD..
I also suspect Hillary Clinton would have made a terrible President, despite my being a lifelong Democrat. I think the Democratic Party in the US needs to replace its current leadership with people who are less beholden to huge corporations. Especially the banking industry, Big Pharma, the health insurance industry, Hollywood, and Wall St.
It is depressing to me how both parties here in the US are trying very hard to divide us when we actually agree on a lot. Poor people in particular should understand how they could improve the outcome by organizing to address their biggest problems. The solutions to some of the worst of it could be straightforward and benefit everybody. (Alternatives to corporate everything)
This is being prevented by wedge issue politics.
I personally also think immigration, legal immigration is a big plus, whats bad is the exploitation of people in artificially disadvantaged situations to extract vastly undervalued labor from people. The so called problems many people attribute to immigrants are really systemic problems with people losing jobs which in the past used to offer people stability both here and elsewhere. The poor people who come here to seek work come because of gang warfare and havoc subsidized US (in the North American case) agricultural products making farming so much less profitable people leave their home lands which is I am sure where most would like to live. If we stopped trying to extract the most wealth out of every transaction and stopped trying to make deals to push peoples wages down lower and lower, if we understood that inefficiency has its plusses and good business practices leave everybody happy they have interacted, we would all be a lot happier and healthier and wealthier too, I suspect.
