Earlier quoted context omitted.
There are plenty of websites where employees share their wages/salaries, which enable direct comparisons between companies. A simple google search reveals such data. Also, for a lot of these jobs, the companies post the pay ranges on the actual job description. These wages aren't some super secret data point. Referencing a 2021 Reuters article as the source for Amazon wage data is an interesting choice, when you can…
When you're working as a professional journalist, a "simple google search" isn't enough: how can you be sure that the information you are seeing on those kinds of wage comparison websites is accurate, and comes from people who genuinely worked at those companies?
We're dealing with uncertainty in all regards. My position is that it's best to be transparent with our uncertainty.
If the article had said "We didn't have good wage data to directly compare Walmart & Amazon warehouse compensation against each other", I would have loved it, because it'd show transparency/honesty/authenticity. Or if they did an analysis using data from job postings or wage sites and were very transparent on their methodology and admitted what you stated "These figures were taken from job postings on X.com, which can often have ranges. Consider there to be some degree of imprecision."
I totally get that it's not a norm in the media today to do that, and there are a lot of structural incentives that create that situation. I can empathize with each actor/individual within the broader system, and that they're doing their best within the world they live in.
