How do we come to the determination that rich people, who happen to be past retirement age btw, are usually in public life? And that's not the same thing as taking a very difficult job.
The question was about "filthy rich" people. Perhaps you should define the term, if you wanna delve into it. But if you go down the Forbes' list you'll have heard of most of them in some capacity. Maybe flip the burden of proof and ask yourself how many filthy rich people are anonymous, and how you'd know that, if they actually were?
Also, note that the job being difficult is not in dispute. You don't get credit for taking a tough job if you don't do a lot of the tough parts. You also don't get credit for it if you don't
know it's tough when you run for it. We've got hundreds of tweets from the last administration talking about all the things he'd do differently if he was President (many of which are inarguably at odds with what's been said and done since), for example, strongly suggesting he thinks or thought the job was a lot easier than it was, as every heckler in the crowd does.
To me, he appears busier than presidents of the past. He always seems to be on the go and I don't recall him taking vacations like others.
I'm not sure how you want me to respond to things like "he appears" and "seems to be." I can't account for whatever 3,000-mile-high impression you might be getting from just seeing him doing a lot of stuff.
As I said, even his critics must admit his energy level is impressive for his age. But constantly tweeting or holding rallies is not an example of working hard. Motion is not action, and movement is not work. In fact, I'd argue most of the real work of being President is by definition the boring behind-the-scenes stuff, so the more I see the President out at rallies and being noticeably in public, the less real work I tend to think they're doing. Most people understand this on some level: it's a running joke that politicians love to get in on photo ops and take credit for stuff, and this is kinda what it looks like. Being visibly on TV a lot is not an example of work, and is perfectly in line with the desire of attention I've been talking to.
I don't think selflessness is the more likely explanation, but it could be an explanation, or at least part of it. Sure, there's evidence of self promotion, but that's not evidence against wanting to help the country or do some good.
Correct, it isn't...but it doesn't have to be, because that wasn't the question/claim. The question/claim is about what he's cared about in the past and why he might want to be President. I don't begrudge him talking himself up (although it can get patently silly, like when he pretended to be his own PR guy and made up flattering stories about himself) or starting a TV show all about him, but it'd be kinda nuts to ignore all that stuff when you ask yourself why he might like to be in the most visible job in the world. One of these explanations is 100% consistent with decades of observed behavior, and the other is just a speculative thing that
could be part of it because nobody can disprove it.
Just wondering why one candidate gets questioned but not the other.
I'm not sure why saying "just wondering" changes what I'm saying about relevance. You are free to wonder whatever you liked, but you posed this question in a response to me, in a discussion entirely about President Trump's character and motivation.
