In What Aspect We Are Equal?

My answer is: in aspect of "value" - the value of life. I believe we are all different in aspect of intelligence, knowledge, wealth, or social status, but these differences should not alter our value of life. Thus we are all essentially equal (not include those life offenders and destroyers) and we all respect each others. If this is well understood, there would be no arrogance, bigotry, power abuse, self-pity, etc..
