There's no need to be defencive, or argumentative or angry.
Just be aware, respectful and educated that everything is not equal.
Of course it is not equal. But while it is true that privilege had nothing to do with their own choices as the speaker described, it is also not the fault of the 'privileged' he identified that they have advantages.
Should those people be expected to use the blessings they have been granted to good advantage and benefit to society? Yes they are and of course they should.
Are those not so blessed still capable of using their God given abilities to good advantage and benefit to society? Yes they are and they should.
The false analogy is that a foot race depends on who is the most economically 'privileged'. A foot race depends on who has the most athletic ability which has nothing to do with economic privilege and everything to do with God given abilities we are born with.
So for a foot race, he could have just as well said:
1. Those who have normal intelligence take two steps forward.
2. Those who are healthy and physically whole take two steps forward.
3. Those who can run fast take two steps forward.
4. Those who have a competitive spirit take two steps forward.
5. Those who are sprinters take two steps forward.
6. Those who are male take two steps forward.
Etc.
The point is that they all were starting from the same point. The person most athletically gifted and used that gift to the best advantage would most likely win the race. The kid from the poorest ghetto but who has great athletic ability is much more likely to be drafted into the NFL or NBA and earn millions than is the less athletic kid who has enjoyed financial privilege.
What we should be teaching kids are the values and qualities that lead to privilege and success and strive for that. And it is a simple fact of life that there will always be disparities among people--some will be gifted musically and/or artistically while others are not. some will have IQs that allow them to understand and excel in advanced scientific or mathematic fields while others will not. Some will have people skills while others not so much. Some will have ability to envision solutions while others will be more suited to be worker bees to make the vision happen but are just as important to the results.
The truth is that life simply is not fair and never will be. But every person can hold his/her head high and be proud of his/her accomplishments when the hand he/she is dealt is played for maximum advantage. The choices we all make are the most determining factor in the life we will lead, and the poorest of the poor financially can achieve greatness while those born with great economic advantage can squander that advantage.
