It is best to evaluate each potential applicant to law school on an individual basis in order to assess whether or not attending law school would be a reasonable career move.
For those with significant student loan debt from their undergraduate degree, it is probably not wise to take on additional student loan debt for law school.
For those who plan to attend law school because they do not know what to do with their professional lives & have no meaningful career path, it is also likely not to be a wise move.
