In any ethnic group, there will always be those who are worse off, but who work hard to overcome adversity. For some it is easy going, while others encounter difficulties; some cultivate their moral character and are careful with what they do and say, while others are confident and active, ignoring minor details; some are worn out with work, while others are born with a silver spoon in their mouth; some die young, others live to a ripe old age; some are rich, others poor. This is life.
However, reliance on a single outlook means to jump to conclusions, criticize and even discriminate against other groups: This is prejudice and bigotry.
