As for the career prospects of anyone fresh out of law school, the legal profession suffered a massive meltdown in 2008 and hasn't recovered.

As for legal work, the median starting salary for the top 14 schools (remember, there is a shortage of 'good' programmers) is still 160K+. How many good programmers start there? Sure lower-grade lawyers don't make much, but neither do lower-grade programmers. Facebook and Microsoft both have reasonably high hiring standards and are complaining about a shortage of people over their threshold. As for 'the rest of us', the average lawyer salary is higher than the average software engineer salary. There are a lot of low paid software engineers too, it's absurd to compare only the highest paid software engineers to all lawyers which it seems you tried to do.
The fact that you can see the average lawyer salary being higher than the average software engineer salary, and still claim there a meltdown in the former industry while the second is struggling for people, just shows how deeply ingrained our cultural perspective of what job markets and compensation for a given career 'should be', and how it skews our perspective away from the simple econ 101 supply and demand curves that tell the real story. Markets are a lot more honest than PR releases from billionare tech executives.
But on a side note I did like your blog post, I just think it's irrelevant to this conversation.
