What is an improvement is information about income and job placement from various institutions and degrees.

It's almost trivial to chart one's income possibilities based on where you graduate from and what degree you get. The knowledge about how to get into a tech job, or a high finance job, or get into medical school, or get hired by a top legal firm is available to everyone whereas it was limited before to those who knew people who knew these things.

We know what cities and suburbs of those cities will lead to maximal probabilities of "success", we know which schools have the highest achieving kids (or the ones with the richest parents), etc. It saves a lot of time to be able to filter real estate listings by greatschools.org metrics before.
