Because Chinese production standards are shitty. It's a function of communism. Go read The Gulag Archipeligo and you will begin to see.

Years ago anon used to kind of sort of like some shows on NPR. Like Click and Clack. But pretty much all of this century they have been complete liberal fucktards. They can flat out fuck off.
