For context, my parents are multi-millionaires who told me they would pay for my education and support me throughout my life.

I have now been in college for 2 years now and they give me about 500$/month for all living expenses. I went to a state school to study engineering and got over 100k bringing my semesterly tuition down to about 2K in scholarships and am graduating with an engineering degree in three years. Since I saved so much money for my family on school I asked for further assistance with living expenses (I live in a rather large/expensive city) and help to pay for flight training. I want to be a test pilot one day and consider flight training to be a part of my education, therefore. They said no and that they needed to be grateful for what I was given and was acting spoiled and entitled.

I figured they were right and stuck with their argument until my sister went off to college this fall. She is going to a very expensive private school (30,000$ a semester) for a liberal arts degree. She is doing a 5-year program on top of this and my parents are giving her 1100$ a month for living expenses on top of paying for her housing. They also recently paid for a producer to help her create a song (she has less than 1000 total listens on Spotify and is not an established singer).

So overall she will receive over 10x more than me. I am pissed. I worked so hard to go to a better school than my sister, for a more competitive degree, and worked so hard to get all these scholarships. Why at the end of the day are they giving her more this feels like such blatant favoritism.

I am now planning on embarking on my master's next year through my school's 4 1 program (3 1 for me). I asked my parents if they would be able to help with my living expenses at the time. Just living with no tuition as I could get tuition paid for by doing research with my masters. They said no because it was not a part of my undergrad degree. Even though it is still fewer years and much cheaper than my sister's.

I am so so angry with them. I feel like they so obviously favor my sister but any time I've ever brought it up I am told I'm spoiled and most people would be lucky to be given what I have been given. If my parents were not able to finically support me I would understand and respect that but like I said they are multi-millionaires and can obviously support me more based on how much they support my sister.

I understand I am not owed anything. It just hurts to struggle to even pay for food (I literally have often relied on the campus food pantry) I have also worked full time while a full-time student to pay for basic living expenses. And it hurts to be forced to do those things when my parents are multi-millionaires. But beyond that, the massive and obvious favoritism hurts more.

Idk AITB (or spoiled brat) for being super angry and jealous?
