Yes, that is certainly a motive for many of these monsters. However, the effect on the "lower ranks" or even pf all those caught in the act remains the same: because they commit a crime, and a most repulsive one at that, they are vulnerable to blackmail and manipulation if there is proof (pictures, videos,witness statements).
So the motive hardly plays a role as long as it is treated as a "proof of trust" that every co-conspirator must provide as a "ticket to join the club" of these degenerate criminals.
As I said, this is a classic strategy of organized crime. And since the current US system is essentially organized crime, just on a unprecedented level, I don't see why the same methods shouldn't be used here.
For the US, the fact that the president's father had proven ties to the mob and that the president's mentor, Roy Cohn, was the go-to lawyer for various underworld figures in the 1970s and 1980s only makes this more likely.
Yes, absolutely, I completely agree: the Panama Papers already made this very clear - and the fact that not one of those who benefited most from this outrageous multi-billion-dollar fraud against citizens was ever prosecuted already showed that both the law enforcement agencies of the countries and the political leadership are so deeply infiltrated that they simply do not fulfill even their most basic duties anymore. In other words: corruption on a scale that one can only conclude that even most of the remaining democracies must be rotten to the core.
And yes, you are also absolutely right with the second point: Nazi ideology has always been closely linked to the interests of business magnates. That is where the term fascism, as originally coined by Mussolini, comes from: autocratic rule by the economic elite.
What I wanted to point out with the example of the US, and specifically the Eppstein affair, is simply another example of how billionaires have now apparently come to the conclusion that, thanks to their corrupt accomplices in the corridors of political power, they are untouchable - and this is precisely how the US president is acting, who should actually have been in prison for decades for countless serious crimes. Unfortunately, he is not, but is now leading the US as the spearhead of international organized crime, which is unfortunately still not called that because, despite its obviousness, it is secured by state pseudo-legitimacy.
