Re the DeVos family, do pick up Jane Mayer's Dark Money if you want a top-notch resource. But that's a big read. There's much else you can read with some google searching. I've known about them for a long while (two decades or so) because of my studies on the rise of movement conservatism in the US. As some links you've posted will note, her brother is Eric Prince, founder of the mercenary corporation Blackwater. This family, along with a few other very wealthy and politically extreme families like the Bradley's, Coors, Olins, Scaifes, Kochs provided most of the seed money to build and expand radical right wing institutions in America. These people (where still alive) had no use for Trump previously. But now they have found him the most excellent tool for getting what they have always sought - the power to eviscerate the social safety net and New Deal arrangements/values, to crush unions, to reverse the civil rights and feminist movements and more recently the gay rights movement, to turn back teaching of evolution in schools, and to fill up their own bank accounts.
These people and others like them came out of rather old ideological roots the precede even Goldwater (the John Birch Society didn't just drop down from the sky). They are roughly representative of what Ike described in his famous letter to brother Edgar:
Quote: "Should any political party attempt to abolish social security, unemployment insurance and eliminate labor laws and farm programs, you would not hear of that party again in our political history. There is a tiny splinter group, of course, that believes that you can do these things. Among them are a few Texas oil millionaires, and an occasional politician or businessman from other areas. Their number is negligible and they are stupid."

And there's a quote to give us a fine measure of just how insane the right in America has become since Ike's time.
