Is it normal that my brother is manipulative?

I'm 26, my brother is 32. We are 2 of 4 children. My oldest brother studders, he's the second child, there's me and then i have a 16 yr old brother. My parents play favorites with my 32 yr old brother, and he knows this so he manipulates them every chance he gets, and they fall for it ...hook line and sinker. He calls my mother and father everyday and tells them every single detail about his life so he can get some sort of praise from them. They feel he is the "golden child" because he has a degree and some mediocre desk job with benefits and a recent gf who is the only gf he's ever kept for longer than amonth his whole life because he's a prick. I am currently unemployed and not a bum- I work hard ot find work and also babysit and do any other odd jobs to pay my bills and dont ask my parents for a dime. He calls them and constantly tells them that i'm a loser and i should be doing this and that and blah blah blah and is always telling me to get out of the house meanwhile, he lived here till he was 27. Not only does he play my parents like a violin, he also is a shit stirrer. He goes to my brother and sis in laws house and then runs over and tells my parents unnecessary things to get them in a fight. He also is constantly comparing his gf to my sis in law and putting my sis in law down behind her back. He's soo competitive and needs the attention of my parents that he'll do or say anything and when he comes over, it's like he's on stage. My parents light up, they think he's like god it's pathetic. You can't do any wrong if you're him. I actually think he's a pompass asshole and if we weren't related would think his character is hideous and fake and would have nothing to do with him. However, my parents feed into it. I have told them numberous times that it's ridiculous and when all their kids jooke about him being the "favorite" my mother gets in credibly defensive and ends up in a huge fight. This evening, my father who worked outside in the rain all day had to sit at his own dinner table and wait half hour..just sitting and waiting for him to come over and eat with us. My father, who pays for that meal... All he talk about at dinner is himself and what he's doing and his life and how great he is and this and that and then makes stupid comments to me like ohhh u should go work at toys r us..i hear they're hiring and when i naturally get offended, his answer is what bc i care..you're mad? Please!!!! he's never ever came over and said hey sis, hows the job search going, what are you looking for? any prospects? anything? nope, he's NEVER done that he's not concerned ...just fake and rude. I'm 26 and come from a finance job and before that was a General Manager so no people lol i'm not dumb and need to work minimum wage. Family is suppossed to be supportive and i've tried all my life to like him, but I just can't- his personality is horrendous and he causes nothing but problems and i dont like people like that-blood or not...what should i do?
