How do you know there are more poor quality products than good quality products being produced? Do you have data on this? Any evidence at all? By the way, there are a few products that kill people produced in every country, even in the USA. I hardly think all American auto manufacturing is terrible because Ford made a few dangerous products (Explorer and especially Pinto). And how do I "call out" the workforce of an entire country?
I doubt that there are more poor products than good ones, but there are more products overall from China than America, and it's constantly publicized when something faulty, deadly, or otherwise flawed comes out of China. Much more so than faulty American products, party due to the much smaller numbers of things in production.
But that really doesn't explain my point, many complaints are related to outsourced work. Actual Chinese companies can put out some extremely nice work, and I'm not against them, it's just that China is also linked to many outsourced American, Asian, or European companies, and people hate China for lowering the quality of the product, rather than the actual company for lowering their production standards and not maintaining the same level of quality they had prior to exporting work.
Generalizations are not really fair, but everybody makes them about something, so why not accept the fact that not everybody will both admit that not everything is bad and stop making generalizations about it.
