Once avian, referring to Microeconomic Theory: Basic Principles and extensions, in "Chapter 3: Preference and Utility" the book reads as balanced bundles are preferred to unbalanced ones. But the question is the point that diagram show is above the Indifference Curve (IC), that is, on higher (IC) we already now that, as it is the assumption, that higher indifference curve has higher utility, then how one can prove that balanced bundles are preferred. In my view, the point should be probed while remaining on the same IC. What is your take on it? Thanks
