Not very many. Consumers mostly go to the store and grab whatever. Very few even read the label.

Critically thinking - If that was the case this wouldn't have been fought in court.

A few google searches show the effect is minor to major depending on product category. I wasn't able to find exact numbers. But as a personal note I would never buy meat labeled "Made in China"

Ranchers I know who have the most to gain form correct labels lobbied to get rid of it, the WTO didn't like it and they didn't see any gain. This was back when Obama was president though so maybe things have changed?

Huh?

There's no law requiring the "made in USA" label on goods made in the USA. US ranchers who don't want to use the label don't have to.

The WTO doesn't like trade barriers, especially US trade barriers, and a strict "made in the US" label is a barrier, so their opposition is a given. If such labels had no effect, WTO might argue against them on principle, but if they did, that would be a reason for WTO to argue against them.

Fine, I took the minute to search: https://www.usda.gov/sites/default/files/documents/Attachmen... "The model results failed to detect changes in consumer meat demand post-MCOOL"
