Made In China

I got a bit board today and decided to see where things I own are made.

Almost everything was made in China.
One item made in Portugal
Two item are made in Japan
Two Items are made in Mexico
Three items made in Canada
No items that I could find are made in United States.

I then checked our clothing, Most of them are made in Mexico, Honduras and Brazil.
My undershorts (two different brands) are made in United States and Canada
All our shoes, and socks are made in China.
Our kids night clothing are made in Philippines and Singapore.
I have three pair of Levis blue jeans relaxed fit, they are all made in different countries
Mexico, Canada, and Spain.
Isn't anything made in United States anymore?
I seriously can't find anything besides my undershorts that was made in United States.

My Chevy Minivan was made in China, except for the engine and transmission; they were made in Canada.
I thought Chevrolet / General Motors was a United States Auto Manufacture. I guess not?
My daughter has a 2016 Ford Fiesta its jointly made in Japan and Australia.
The engine, transmission, and electronics are made and assembled in Japan.
The rest of the car is made and assembled in Australia. Then shipped around the world
Ford Escorts were made in Germany and Australia, not one was made in the States.
I thought Ford Motor Company was a United States Auto Manufacture. I guess not?

Just wondering:
They say the best things are made in the United States.
If that's true, then why isn't anything made in United States anymore?
