I've had great American knives, great Chinese branded knives, great American Chinese-made knives and bad knives of the three categories. Some examples:
It's a matter of choosing wisely
informing yourself before purchasing
knowing you'll get what you pay for, most times
and act within your budget and options
Can't complain at all, I love Chinese knives as much as my US, Swiss, Spanish, Taiwanese or Japanese ones.
Cheap and expensive, high class or budget
All countries are comparable, all of them have bad stuff and good stuff
Ethics apart, China is one of the best sources of cutlery nowadays
by discarding it you're just losing many interesting options
I talk from years of using, hoarding, buying and having knives
