Really I don't think you'll find absolute freedom anywhere - unless you're squatting in a national park and hunting wild game with a bow and arrow.
What you have, living in a society, are different kinds of rule sets based on which society you're in and which values are seen as most salient. We tend to see equality of opportunity as the most fair and sensible way to go, just that obviously there's no legislation that can make someone free of their genetics - ie. if their genes say they'll never be able to be a professional sports figure, a NASA scientist, or a famous musician there's no legislation that can make a person's wishes come true in that regard; that's just life. Really I think that's why any argument in favor of equality of outcome fails - it attempts to turn the topography of the real inside out to fit our preferences.
If you're referring to what's on the cutting edge right now - it's getting tougher to tell at this point, with the remaining inequality arguments that are on the table, how much of them are natural vs. cultural and if so which to what percent. Freedom to be educated, grow and achieve as we choose, and pursue happiness seems like its a gold standard for a happy, successful, and stable society. Regardless I think equality in the eyes of the law is about the only form of equality that can be guaranteed - past that the favorable arguments for enforced equality start to diminish, particularly once it's agreed that historical wrongs and inequalities have been largely worked out.

I use the word "love" here not merely in the personal sense but as a state of being, or a state of grace - not in the infantile American sense of being made happy but in the tough and universal sense of quest and daring and growth.” - James Baldwin
