Regardless of interpretation, I'm pretty sure deciding whether a kid is fit for the elite/intellectual track or the physical labor track at the tender age of 10 based on whether they can do some tests is not in the spirit of "all men are created equal" And I would agree. But your earlier comment seemed to imply a much more absolute stance. That's what I would disagree with.
