If you had paid attention, instead of assuming, you would know that not just some Dem, but Kamala Harris, has spouted the basterdized version of Karl Marx's quote "What can be, unburdened by what has been" on numerous occasions in public. Just get your head out of the sand!
Like I said earlier, you can waste your time criticizing what I think if you want, but my opinions on Trump are irrelevant. Not being American, I can't even cancel your vote. I just have a lot of fun pointing out what a nitwit he is. This is in fact a very sad situation that the US finds itself in.
As for his wealth, good for him. My understanding is that his valuation is based mostly on the value of the real estate he owns/controls and I have been given to think that it was his father who accumulated most of that. Once you own land in the right location, it's not a matter of great business acumen to become wealthier. But it might be a measure of his competence that a casino of his went belly-up, but I don't honestly know the financial details of that. I have heard many times that American banks won't lend him any money, ordinarily that's not a good sign.
On that subject, don't you find it just a little bit odd that a real estate billionaire is on TV hawking sneakers, watches and Trump coins? I mean, why bother, can it really be worth his while?
As for Harris's quote, of course I missed it, I don't often watch US news. I do however reiterate my opinion that attributing Marxist ideology to US politicians is delusional and yes maybe even deranged. The recent revival of anti-communist rhetoric seems like a reach to me. But maybe I am misunderstanding you, maybe you're criticizing government largesse towards the rich, like tax concessions to encourage Amazon expansions, kissing up to pro sports franchises, raising tariffs on less expensive Chinese EV imports to save the butts of manufacturers stuck with unsold vehicles, including wildly expensive fetish trucks. I'm not saying that there aren't things wrong in the US, e.g., your apparent inability to have an adult debate about immigration for one, but whatever problem you're trying to fix, Trump ain't your guy. Isn't that obvious by now.
