I probably wouldn't have got into the university I did or have the career I have if it weren't for SATs. And no, I didn't have wealthy parents who could afford test prep courses. My prep consisted self-directed study using off-the-shelf test prep material. As a way to discover scholastic talent in populations that is otherwise invisible, it does a good job. If the goal is to discover "talent" that somehow is impervious to measurement of any kind, of course testing is bad at that. But then again the premise seems suspicious.
