Sit down and have a talk with them about these issues, and why you think they are unfair, but remain calm even if they start yelling. In an argument, the winner is almost always the person who keeps his/her cool. Make sure to mention that your brother is getting better treatment than you and express what negative effects these rules have on YOU. My experience in these kind of situations is even if they deny it and say you’re just a complainer, 75% of the time, they are aware they are part of the problem but don’t want to admit defeat. In general, bringing up your problems with their rules may make progress on the issue even if you guys don’t come to any formal agreement.
Also, may I recommend treating them in a polite and courteous manner? If they give you a rule, even if you think it’s stupid, you need to follow it just to be respectful. Your best bet to change rules is not to rebel and don’t follow them but rather to act like a responsible adult and follow them, then meet with your parents and express your frustrations with the rules later on, hopefully getting change (that’s how laws are changed in this country – you don’t see people yelling at guys who are smoking in public places, but rather they go to their local governments and propose a ban of smoking in public places). If you show responsibility, most logical parents will give you privilege.
Finally, since it seems like you don’t really like your parents, find ways to get out of the house and get away from them. Since they don’t allow you to “hang out” after school, you may consider joining some clubs/sports/study-groups where you can socialize and be away from home (in the summer, consider going to/working at a sleep-away camp—you’ll probably have a later curfew, and overall more freedom, and if it’s your job, you’ll earn money). Find ways to get around rules like that.
Sorry that this answer just seems like a bunch of random thoughts thrown together, but here are some more tips:
1) Ask your parents EVERY DAY if there’s anything you can do for them/help them with
2) Tell your parents you love them EVERY DAY, even if you don’t mean it.
3) If the situation becomes any worse, you could consider bringing it up with a social worker/physiologist or similar person at your school. Most schools have them and they are designed to help people who are having problems like these in their lives. I don’t know what they could physically do to restrain your parents, but I’m sure they could give some kind of help.
If I haven’t summarized it enough, act as responsible and adult-like as possible. If your parents have any logic, they’ll start giving you more freedom if they feel you can handle it. If they don’t have any logic and this doesn’t work, you may just have to deal with them until you’re 18, but that’s life: sometimes you’ll have to deal with complete assholes and the best you can really do is suck up to them and wait it out.
