The Nazi and Mussolini comparisons are also apt and useful. These people really are actual fascists in any meaningful sense of the word.
But if you want to anticipate and counter what’s coming, don’t think of Hitler annexing the Sudatenland. Think of how private equity buys up and then strip mines business after business, destroying the business and harming every human connected with it. As @pluralistic puts it, people with “an unerring instinct for making people miserable while making money.”
