So sure! If all we are looking at is ROI then you are right! By definition! As long as you restrict your refutation ("by that metric") in a way that ignores the additional metric I had been trying to add to the conversation. I was trying to point out that there are other metrics that matter.
Is the unique loss you identify not accounted for in the traditional ROI expression?
>> Why would people make an investment with insufficient ROI (Return on Investment)?
> Insufficient information.
> College Scorecard [1] is a database with a web interface for finding and comparing schools according to a number of objective criteria. CollegeScorecard launched in 2015. It lists "Average Annual Cost", "Graduation Rate", and "Salary After Attending" on the search results pages. When you review a detail page for an institution, there are many additional statistics; things like: "Typical Total Debt After Graduation" and "Typical Monthly Loan Payment".
> The raw data behind CollegeScorecard can be downloaded from [2]. The "data_dictionary" tab of the "Data Dictionary" spreadsheet describes the data schema.

> A Euclidean vector is thus an equivalence class of directed segments with the same magnitude (e.g., the length of the line segment (A, B)) and same direction (e.g., the direction from A to B).[3] In physics, Euclidean vectors are used to represent physical quantities that have both magnitude and direction, but are not located at a specific place, in contrast to scalars, which have no direction.[4] For example, velocity, forces and acceleration are represented by vectors
