But it sure helps. From Slate's Emily Bazelon:
Comparing Miers to the woman she would replace–Sandra Day O'Connor–underscores why you don't have to be snooty to think she's a let-down. O'Connor graduated from Stanford University with high honors and, in 1952, at the top of her class at Stanford Law School. Miers got her undergraduate and law degrees from Southern Methodist University, finishing law school in 1970.
How much does going to a particular college matter in predicting income and/or career success? One answer that SMU grads who turned down Stanford will find appealing here.
