At the risk of inflaming political sentiments, I do feel I need to somewhat come out of the closet to respond to this one.

When you use it with a different meaning, that means that if someone actually advocates equality of opportunity (e.g. everyone starting in life with a specific identical sum of money, and similar education, without ability to be helped by their parents or other family connections) they don't actually have a way to say it. You've usurped the phrase.

But I do advocate equality of opportunity under nearly precisely the terms you define. In a ideal world material starting conditions would be identical and access to self-enhancing technology would be trivial for everyone. Differences would be the result of inevitable differences in actions that would result from all the different kinds of values "people" would choose, and even then I'm practically imposing a cap because as I've clearly stated in previous posts I believe in diversity and don't think uberefficient values or designs should be allowed to gobble up (or paper-clip so to speak) everything. I hope the universe will eventually be divided between, many patches of interesting individuals and/or societies with different values. And yes I'm perfectly ok with one patch/individual/society looking at another and not approving of what they see, but I would ideally like them to live with it.

Even in today's world, the very very non-ideal one, you'll find I'm quite ok with a lot of wealth distribution and some other interventions. You'll find few objections to well thought out universal health care or free education (all levels) schemes from me.

The only real thing I can't negotiate on is meritocracy when it comes to natural talent and culture. Natural as in genetic or very very difficult to change traits that are passed epigenetically. We don't have the tech to change either right now, and I think redistributing research positions on considerations others than "best person for the job gets it" will clearly set us back on getting that!

And let me be perfectly clear I am generally not ok with people being forced to change their culture or genes (once the tech is there). But I do think that to prevent society from going into a caste system with no ways to change casts if one so desires, free or very cheap genetic engineering and memetic interventions will have to be made available to those who choose them. And those who don't choose them should never be worse off in absolute sense, but they will have to accept larger relative levels of inequality as time goes on. Especially if they choose to remain unmodified humans.
