He sounds like it's not just anger. He sounds kind of controlling. My dad use to act like that toward my mom, hell he still does (granted he can hold a job, he's had the same one for twelve years). It's not something a kid needs to be raised around. Personally, I think he should shape up or ship out, but that's easier said than done and much easier when you're just a 3rd party observing like myself. I wish I have good advice for you. I can tell you that with all of the verbal abuse, my mom did go to work, she did start to make something of herself despite my dad's constant insults. I don't know how she did, but it proved to me that it is possible.
Wishing you the best.
