The EPI estimated about $50 billion per year in wage theft back in 2014 which would equate to about $65 billion today. It could also have changed a bit since then.
Summary: There is a normal percentage of theft compared to previous years, but because of inflation the estimated dollar amounts are “unprecedented.” Please don’t ask about the unprecedented profits.
Clickbait headline articles need to be shocking sounding. Bonus points if they push the narrative that companies are good and us horrible peasant thieves stealing from them are bad.
It’s worth noting that when retail sales go up, as they did in 2022, shrink also tends to rise. The average shrink rate in the 2022 fiscal year was 1.6%, up from 1.4% the year before. The latest figure is in line with shrink rates from 2019 and 2020.
Just a correction: wage theft accounted for up to $50 billion in 2014 according to the EPI, not 2017. That would be roughly $65 billion today. Like you, I would also like to see more recent numbers.
All I'm saying is that if I'm doing self-checkout, and something I'm buying is missing its code, it's probably going to be the cheapest thing I can get to go through.
I’ll bet these companies throw everything under the sun into the theft bucket. That includes internal mishandling of inventory. They then exaggerate the costs for insurance claims. 
Maybe they can all go to an instacart model or something like Amazons auto checkout model. Or just have actual cashiers. Maybe everything is in vending machines. Idk, but the current experience in retail mostly is horrible and I want to avoid it if at all possible.
Apples and oranges. If you are a cashier and theft occurs you aren't paid enough to risk anything, including your life, to stop theft. Companies can hire more asset protection people.
