@MT1982 I don't think it's entirely subjective. YOu can quantify what the differences are in quality and break it down(which I can't do), and go from there. So I do think it's more objective than you think.
Respectfully disagree. There's a reason why you can't do it... Anyone can claim to quantify, but in the end they are making an evaluation based on their own valued variables. For example, the "quantification" of a single person with no debt making $500,000 annually may be significantly different than a family-man earning $50,000 annually. Too many subjective variables for one to claim objective quantification, imho.
