This. The one off things, ignore. It's better to be an adult and not be beholden to your parents to pay for your new tires or whatever else. You do have a point with the family trip that they are having you pay for, but not your siblings. It'd be a wonderful gift if they could treat you all.
My DH's sister has needed her parents to bail her out of many financial messes. They used to pay for her to join family vacations too. While it would sometime irk me, because I'd see her buying new clothes or a new car, I choose early on to just let it go. It's her parent's money to spend how they want. I would have never wanted to trade places with her, because of course they feel they get a strong say in how she lives her life and I would hate that.
