This clip about sums it up:
“Let me explain further. I don’t mean to insult paralegals out there – you do a great job (some of you) – but don’t start to think that you’re “better” than JDs. The paralegal students I taught, at an ABA-accredited paralegal program, found it hard to understand basic legal concepts, wrote like middle school kids, lacked motivation, and were doing this because they had nothing else to do with their lives. A couple were highly-motivated and smart, but most weren’t. Most were rather stupid to be honest. Most just didn’t care. The work I graded was embarrassingly bad.”
