Some do and some don't. There's low-paid "unskilled" work that's still backbreaking.
This. Also it completely depends on how you define the word "hard"
Who works the hardest physically? Probably migrant farm laborers, possibly the least paid people in our society. And they NEVER get tipped.
On the other hand, most very high paying jobs rely on mental work. There are some exceptions like professional athletes, but most highly paid jobs rely more on "mental work" that often takes a longer time to develop the skill set for. So it's a completely different kind of hard to work away on a tough problem compared to being able to mindlessly pick crops, even though the latter is going to be way more physically exhausting.
If we paid people by how physically hard their jobs were, we would have zero scientists, engineers, programmers, etc. and everyone would try to be a farm laborer or construction worker or something.
I may not go down in history, but I will go down on your sister.
