You're looking at this from a cashier/stocker perspective only.. store view only. If Wal-Mart only employed "low skilled" employees, they would cease operations in a heartbeat. Preventable has the better perspective.
Wal-Mart, fast food, some grocery stores, anything that relies on selling more items at a lower profit margin will pay less and offer less benefits. They also expect more efficiency out of their employees and are higher stress environments. Working fast food is easier when there are 20 people packed and each worker only doing a couple things.. but when it trims down to 5-8 people running the whole show, it takes real skill from every person to be winners. And for what? $8 an hour.
Glassdoor reviews on Wal-Mart's benefits even have managers+ reviews that the health coverage is costly and not very effective. Compare that to Amazon. My one exception for fast food might be Chick-Fil-A where they have higher profit margins, simpler menu (much more efficient), overly staffed, fast service, etc. I've not looked at their benefits extensively, not great for part time workers. They offer 401k, health, PTO, etc. And they're worth like.. 6-7 billion. Your theory is trash.
And you can claim "highly skilled" all you want, but it doesn't mean your skills are transferable. You can also continue to believe that FedEx is prestigious but that's debatable. Just because someone gets a job that you would snub your nose at, does NOT mean they're uneducated.
You always find a way to look down on other employers and workers. Taking a job that you find miserable might not be the best decision for someone but maybe they have bills to pay and it's the only place hiring. They may also not be at their best (because of stress or life events) and may miss better opportunities. You are ridiculous and aren't even worth the time of day for real conversation. I come back to your foundation every time oldfart, you're privileged, opinionated, and a judgmental as5hole.
interesting read, fedex + "skilled" = debatable; according to your opinion of other places of employment.
