Hourly rate would be absolute crap just check the movie special when lit, has a lot of stern factory footage not one Caucasian in 5 mins of footage. Cheap migrant labour

Just because they look Hispanic doesnt mean they are migrants !
There are probably 30 or 40 million plus Hispanic looking people who were born in the USA, minimum.
Also, I have been to areas/suburbs in the USA, where the majority of the people in that area are primarily African American or Hispanic or White.
Perhaps Stern is close to a large Hispanic community. Its not like Stern is on the border with Mexico 20 minutes away, its in the middle of the country. I have seen many caucasian people working on the Stern line in many videos. Perhaps they pay their people well, who knows ? It may not be minimum wage. Alot of the people out in the production area have been there for many years.
