I want to say dramathrowaway's story holy smokes is one of the worst family accounts I've read. So sorry you had to go through that.
In my family there was favoritism of the boys. Some examples the boys got allowances. When we asked for an allowance our Dad said, what do you need an allowance for? If you need something I can buy it. We had chores we had to do, but did not get paid for them (one of them was making all the beds, including our brothers' beds). However if our brothers did the exact same chore (shoveling snow, mowing lawn) they would be paid.
On my mom's side, my mother was the first born, but then about 5, 7 years later her 2 little brothers came along. She was very bright (read every book in her branch library) and told that they would make sure she would go to college. When it came time to go to college my grandparents said of course she's not going to college, they were saving any money they had so her brothers could go, and she should just move back after high school and get a job to help support the family and her brothers. Maybe that's what would have happened. But my great grandmother said that was nonsense she was the smartest of the bunch, and paid the college costs. And while my Mom did inherit some significant assets from the great grandfather, I don't think she got anything of note when either of her parents passed away.
On my Dad's side, my grandmother was widowed young. Even though she was considered middle class, her husband both due to business losses occuring when he was sick, and from pride, made sure to pay all his debts before he died, leaving the family with nothing (not even a house). Raised two sons with great grandmother's help (who was also widowed young). She immigrated to the US, brought both of her sons over eventually and gave them all the money she had saved from working at a sweat shop for 5-10 years. Luckily the brothers were successful so she lived with us or our aunt and uncle the rest of her life. She still was so frugal that if she got a bar of soap as a gift, wouldn't use it, but display it on her dresser.
Anyways whenever there is a crisis our mother often wants us two girls to drop everything to help "the family". This has happened to my sister multiple times since she lives closer. I understand my mother was raised to feel that females have less value, or only value in regards to how they could help the family, but no, not going to keep that going. She has a number of jewelry pieces that were willed down to us from our great grandmother. She agrees they are ours, but also will not give them to us, because "she might need to sell for financial reasons". Financial reasons including making sure my deadbeat older brother, who lives off her, has cable, xbox, and cigarettes. I'm thinking the likelihood that my sister and I will inherit anything of value from either parent is slim to none.
