In the end, who cares WHY it works out that way, as long as it does?
First off, let me point out that you didn't address my point on the anecdotal nature of the evidence.
With regard to the WHY, if there's an independent reason that's causing the correlation but you don't take that into account, then there's a good chance that things will no longer continue to work out that way.
Say, for example, that the people you know who are lawyers happen to be the people you know who are smart and motivated. They would probably have made more money regardless of whether or not they became lawyers. If, however, you say that the important thing is that they are lawyers and not that they are smart and motivated, and this leads people who are not smart or motivated to go to law school, then your observation that lawyers make more money will no longer hold true, at least not to the same degree.
