The key word is really just quality control, I don't care who makes it or where
You got that. As for brands, just search on the Menu Pet Foods and see that this one pet food maker was producing dog food sold under 53 brands, and cat food sold under 42 brands.

There are actually very few manufacturers out there, but there are lots of brands.
So why should anyone have to buy a knife manufacturing plant when there are facilities and people available for use and looking for work? If you subcontract with a good manufacturer, that plant will have a Quality Control Department. The quality levels are negotiated along with the price. The people in the plant get paid, they go home and feed their kids, and you get a good product, or you walk. The subcontractor knows that and wants repeat business.
I was just looking at dishwashers. Do you think Kenmore makes its own dishwashers? Do you think Walmart owns its own vegetable canners?, owns its own refinery and bottles its own oil?
A bud of mine operated a canning line in a motor oil cannery. In ancient times, oil came in cans.
He said every brand of oil, except for Penzoil, came off his line, all filled by the same 30,000 gallon 10W-30 tank.
The people who paid more for a bright red label on their oil can thought they got more for their money, but they should have spent less and received the same stuff inside the dark green can.
