The Importance of Being a Consecutiveist

I wonder about this if the view is that actual possible future people also people who will exist that don't yet exist are equal to us. If we think humanity's going to exist for a long time and so we get better by the sun it seems like given how strong those interests are maybe you don't have to do a tutting up exercise. I just want to question that claim that everyone has equal value or equal importance why do you think that's the case everyone is?
