From my point of view none of them are, and that takes me to the thought that probably, nobody is, there are always circumstances, family, money, careers... so why challenge with the title "Freedom"? What do you think the author is trying to say with it?
What do you think of what is happening in the book? Do you like it? Do you find it realistic? Because I think that Franzen ultimately wants to be realistic, but to me, maybe they are all too extreme and together tied by a fine rope, it just sounds like too much at times.
