So only physical labor constitutes hard work?

Physically strenuous jobs are associated with higher rates of disability after retirement and earlier deaths, despite the link between physical activity and improved health outcomes. So while not discounting the effort in other types of jobs, I think it's fair to describe work that literally shortens your life outcome and makes it more physically painful as "harder".

I can't imagine what it would be to be rich. I know what it's like to be me, and my life has its rough spots. I know some of the rough spots of the poor - although a lot of that is from TV procedurals and movies.

I doubt that anyone has pondered about being rich with their problems, because all the benefits seem to outweigh the problems. I thought about it kinda hard before I posted that item.

Not WORSE than poor people - but different. And still rough. And yes, I certainly agree that if I had to be miserable, I'd rater be rich and miserable than poor and miserable. But the problems are there.

I can agree that money can't buy happiness. That has been backed by scientific research. I can also agree that everyone has problems and those problems are important to them. But you said:

Which is so risibly stupid as to be offensive. Do wealthy people have their own set of worries like everyone else? Most definitely. Do these worries involve not being able to afford college for their kids? Being one layoff away from losing their home? Not being able to pay a medical bill because insurance won't cover it? That's less likely.

But you know, they do have to worry about hiring an accountant, lots of dirty windows in their multiple homes, getting asked for donations, and boogeymen ransomers. 

Until I experience it, I can only speculate about problems of the wealthy. But I feel certain that those problems exist. Perhaps with less notable frequency in the world, simply because there are fewer rich in the world than poor or middle class.

I may also have misused "more"; perhaps it should have been "as much, in different ways."

It seems, my friend, that we must agree to disagree; I speak on speculation, not fact. I hope you DO speak on fact; on your behalf, it'd be nice to be rich, even with problems.
