The real issue with this type of article is that it doesn't take into account that the same logic applies to every other profession. Is it hard to start out as a lawyer? Yes. Does the person who pulls the longest hours and works the hardest succeed? Yes. If you lose a big client is it possible you will be find yourself without a lot of work to do? Yes. Do some lawyers feel disillusioned with their career choice? Yes.
However, you can write the same exact article about a Doctor, Businessman, CPA, Psychologist, Dentist, etc.
Harvard has a medical school, a business school, etc and graduates of Harvard Business School will have more opportunities than an MBA from Santa Clara. Are their doctors that are disllussioned and want more? Yes.
I don't think anything the article says is necessarily inaccurate, but the simple fact is you will run into the same issues no matter what profession you choose. Additionally, you can succeed from a lower ranked law school if you know what you are getting into.
If you go to Whitter Law School you are not going to become a partner at Cravath just the way it is, but can you be a D.A, City Attorney, Family Lawyer, Litigator, etc yes you can and there are numerous lawyers from Whitter and other "low-ranked" schools that are happily employed attorneys and plenty of other Whittier grads that are misreable or unemployed.
The simple fact of that matter is I could talk to anyone on the Ferry I am currently riding and I guarantee everyone of them will tell me they are overworked and underpaid. That is just human nature, but I can say I really enjoy my job as an attorney I don't make as much as I would like, but I am excited about work everyday because I knew what I was getting into.
Therefore, I think if someone really wants to be a lawyer and has realistic expectations it can be a great choice, but if anyone thinks getting a law degree leads to exorbitant riches and constant excitement they are mistaken. Every job has boring aspects to it and the life of a lawyer is no different than any other profession.
