Well at least you were open to changing your opinions based on facts and reality. There are so many who really live their lives based on assumptions, and projections. China is, and has always been capable of producing high quality products. The biggest difference between China and US manufacturers is that China is more likely to knowingly allow a defect to leave their doors ... Why? Because they have an intense fear of loss, because they struggle more than we do to gain.
I see and experience this time and time again with Chinese manufacturers, and vendors a like. They all focus way more on what it is they stand to lose, as opposed what it is they stand to gain. They place profits before reputation, and this bass ackwards mentality keeps them in a place that doesn't earn them the respect, and professional standing that they desire.
I have empathy for them though, because this has a lot do with the culture, and most especially the government rule they live under. They are forced to sneak around to gain access to, and participate in many things that we all enjoy freely, and without second thought. Living this way deeply affects how they perceive, interact, and relate to the World around them. Just yesterday I was told that China was cut off from access to google .. google of all things? Now they have to scurry around on proxy IP's just to open their friggin gmail accounts .. that's deep.
