I suspect we agree. If you could universally define "better life," you could quantify it. But you can't. We're also bad--really bad--at analyzing ourselves. Right now, I'd love to be spending 60 hrs/week programming and less time writing papers. But I bet I'll feel differently in a decade.
> And no. College is not optimizing its graduates for a better life. College, since its inception, has assumed that you came in with one.
I'm not sure what you mean. Higher education has become increasingly accessible to the economically disadvantaged, not less.
Also, here's Harvard College's mission statement:
> Harvard College adheres to the purposes for which the Charter of 1650 was granted: “The advancement of all good literature, arts, and sciences; the advancement and education of youth in all manner of good literature, arts, and sciences; and all other necessary provisions that may conduce to the education of the … youth of this country….” In brief: Harvard strives to create knowledge, to open the minds of students to that knowledge, and to enable students to take best advantage of their educational opportunities. To these ends, the College encourages students to respect ideas and their free expression, and to rejoice in discovery and in critical thought; to pursue excellence in a spirit of productive cooperation; and to assume responsibility for the consequences of personal actions. Harvard seeks to identify and to remove restraints on students’ full participation, so that individuals may explore their capabilities and interests and may develop their full intellectual and human potential. Education at Harvard should liberate students to explore, to create, to challenge, and to lead. The support the College provides to students is a foundation upon which self-reliance and habits of lifelong learning are built: Harvard expects that the scholarship and collegiality it fosters in its students will lead them in their later lives to advance knowledge, to promote understanding, and to serve society.
That's pretty damn well summarized as "we empower our students to lead better lives." We can argue over whether college comes close to achieving that goal, but I'm comforted by the fact that the stated mission at least aligns with my personal reasons for attending school.
