There are very few top tier Wall Street or White Shoe law firms hiring the top 2% of graduates from the top 10 Law schools at 6 figure salaries. This especially goes for frum first year associates who would not slave away and bill thousands of hours because of Shabbos and Yuntif restrictions.
I think you’re exaggerating. At least 70 percent at a top ten school can get a job paying 160000 first year (and far more after that). And closer to 90 percent at a top 6 school. And there are hundreds of frum lawyers at these firms.
