Is it okay that my dad is not letting me do ANYTHING?

okay I'm 16 and my brother is almost 21 and I want to get a job and he won't let me, he said that getting a job will keep me from him this summer (my parents are divorced, and they both get half of the summer) and I can work with him, well that means I'll be with him all the time when I should be home with my mom, and he does back breaking labor and my back kills for a week after I work with him (he remodels houses) and he always yells at me on the job. And I'm supposed to get my palatal expander off in a couple weeks and it's driving me crazy and causing a bad infection and he said no I can't get it off for 6 weeks (should be 4 weeks) because he has me and he wants to go to our cottage in michigan. And, the first saturday of every month I have a ghost hunting meeting and he doesn't let me go cuz it's "his time" and he doesn't want me going. Also I can NEVER go with friends when I'm with him, cuz its 'his time' BUT when my brother was this age he didn't care about ANYTHING he let him do whatever he wanted. Why is this happening? I'm so pissed off I can't do anything at all. I tried talking to my mom she's no help at all. please give some advice I have all this anger built up inside of me and Idk what to do with it. also I had 2 applications filled out and I wanted him to take me to drop them off that's when he started yelling at me that he doesn't want me getting a job. I really need money , I want to get a car in a few months. my mom doesn't have a ton of money and I want to be able to have and work for my own money. My dad doesn't give me money, unless I work with him which I don't do.. he won't even give me 10 bucks to go to the movies with friends.. and now he's yelling at me as I type because he's telling me what he's making for dinner next weekend and I said ok it's like 2 weeks away.. he's so mean to me someone please help it's like hell here :'C
