how is it hard to understand? 1) If they authenticly make "bad" lawyers then by comparison you'd look good
2) He's better off making money as a lawyer then not
1. This is exactly what is wrong with the legal profession today. There are way too many lawyers out there giving good, intelligent lawyers a bad name. Like the medical profession, the legal profession should strive to provide a higher quality of legal services rather than a higher quantity. Many variations of this same argument have been hashed out millions of times over - I'm not going to re-hash it here.
2. "or for sure going into debt working in some broke factory"
How did this hypothetical factory worker get into debt in the first place? Most factory workers do not have a college education and therefore have no debt when beginning their jobs. If the factory worker has no debt, then at least he's only paying his rent + utilities. On the other hand, consider an attorney who has significant debt from both college and law school. The attorney is only making enough to pay off his rent, his utilities, and the interest on his loan. At the end of the day, sure the attorney has made more money, but he still owes the principal on his loan and is no better off than the factory worker.
Sometimes you just have to think with your head. I don't think you really comprehend what it's like to pay 8% interest on $120K student loans while working a $30-40K job, paying rent, taxes, and utils.
