Sad to see some of the responses.

Reading the last words of the poor dr., how can someone doesn't fell the sorrow, the powerless, the sorry to his old mother? Even his is my worst enemy, I still couldn't stop feeling sorry for him.

Not everyone will be lucky as you on making money and wealth. There is always large chunk people struggle in the bottom of the sociaty. Sure, themselves are to be blamed the most. But they alredy suffered greatly in the unforgiving sociaty. Why someone still enjoy blaming the dead? It's like someone enjoy hearing the last scream of the lamb, since the lamb are stupid and deserved to be eaten by human. If someone to be blamed at this moment, it should be god or nature that created the un-equal world.

Lack of sence of justice and compassion is one of the biggest Chinese education failure. Maybe it part of Chinese culture. That's why for the most part of Chinese history, we are in a man eat man sociaty.
