"Excuse"? You think people are being too lenient about the warehouse workers? Those jobs are awful, and it's not about simply being a physical job. I would much rather do carpentry.

There are a lot of awful jobs. Roofer in Phoenix in the summer, for example.

No, I don't think people are being too lenient -- it's a bit more subtle than that. There are many physically demanding jobs, some as much or more so than warehouse worker. I was questioning why we never see people say people in those job families couldn't possibly study after a day at work.

What you want to do is also irrelevant, as you might have an enjoyment of carpentry. Me, I hate it, and would rather be a warehouse worker.

Amazon warehouse jobs aren't just physically demanding. I agree that one can study hard after half a day spent on some physical effort. Instead the problem is that Amazon pickers are under constant stress all those hours to meet targets far more demanding than most other jobs. I would expect that constant mental stress to leave people so frazzled at day's end that they would be unable to hit the books and concentrate.

> far more demanding than most other jobs

And you've just made my point for me. "Most" other jobs. It's not the most difficult, most physical, most dangerous. Where are the people saying people in job "X" can't possibly study after a day at work? Somehow, that reasoning is confined to warehouse workers.
