If the expectation of the job is to "type meaningless stuff at a computer desk", doesn't this point to a problem with the expectations of the role? I would submit that if the work is truly meaningless, and it often is in my experience, it doesn't need to be done. Of course anyone would choose a pleasurable activity over meaningless, mundane busy work - regardless of their unique expression of the autism spectrum.

I also think that there are many wage workers who do not revile that existence. My intuition says it is more common in "office jobs".

I think the implication is that someone without autism can recover from these stressors more easily. And they tend to be able to absorb these stressors with less of an impact on their mood. People without autism have more control over when their brain is engaged with something, and have to expend less effort when exerting that control. It's not just about physical energy.

The brain of a person dealing with these types of symptoms is kind of like an engine running near red-line 99% of the time. When someone is masking, for every thought they express, there were likely dozens you didn't hear or see expressed over the course of a short social interaction.

Other times, they are caught in mental loops. Reading the same line of text over and over, or replaying someone else's comment over and over, and not comprehending because of an auditory stimulus that is monopolizing the comprehension processes within the brain. When this happens, it's easy for them to miss important context or body language when working with others. That requires even more masking to cover up because it's a social faux pas to admit you missed something important. So then your brain goes into overdrive trying to derive the missed information from followup conversation.

Using sustained, intense thinking to overcome challenges that others don't encounter as often can become the default coping mechanism for this kind of thing. It's not something that is easily noticed, because it's part of masking, but it tends to be more draining than many people realize.
