Freedom of choice is for the most part an illusion, it is only true freedom if you determine what's on the menu. To be able to choose 'left' or 'right' when you want 'straight', 'down', 'reverse' and so on as valid choices but you don't have them because of the constraints placed on you by every day life is a false kind of freedom presented in those limited choices.
So, in practice, your average billionaire has more (many more) choices available to him than those lower on the financial ladder. The reason Jeff Bezos had the choice to give that speech or not is not because he's particularly happy, but because he's rich.
