Interesting! I'll admit to not watching Kane for a while now but I found a lot of relevancy to modern times in it. You still get the powerful and wealthy with their megalomania and penchant for extravagance. You can see people like Murdoch, Trump and Musk in that character. Just look at the images of Musk as he walked into the Twitter offices with a kitchen sink! Pure Kane, in my opinion.
I think Trump especially fits that role quite well. Swap the zoo for golf courses with gold embossed, fake coats of arms and Xanadu for Mar-a-Lago. Then you have the Trump lackies who are expendable, just like in Kane. The trophy wives, both have locked down . Even Trumps demeanor seems to be modelled on Kane, i.e. aggressive over-confidence and lots of macho pointing in hustings . I don't know if Trump has a sled, though.
Personally, first time I watched it donkeys years ago, I was unaware of its kudos as supposedly the greatest film ever made, but I was entranced by it. Time I dug it out again, methinks.
