This is going to be really long, TL;DR at the end.

I'm (26M) living with my parents due to highly messed up economic situation in my country. My family was always comfortable and me and my sister didn't see any real economic struggle.

I started earning money at 13 with my hobby, and I wanted to move out when I hit 18 and got a full time job with my hobby/profession. Economy was not in the toilet back then and I could afford it with the job I was passionate about.

I talked about it to my parents and they got mad, said things like "go mess up your life if you think you're burden to us" but I never said anything like that. I just wanted to gain some experience on managing a wallet and a house on my own with the comfort of knowing my parents would be there if I'd fail. They didn't support me, so I couldn't move out.

Same thing happened when I was 21, 22 and 23. They didn't even answer me after a point, just straight up ignored me. I just asked for their help for the initial expenses because it was starting to get too much for me as the economy slowly got nuts.

My sister is 4 years younger than me. I always treated her with kindness and love. When my parents didn't understand her, I talked with her to comfort her. I supported her in every area of life. I was there for her friendship dramas, relationship issues, I ocassionally gave money to her even if she didn't ask for it. I would hear her cry and immediately go talk to her, listen to her. I would play games with her, give book and movie recommendations, share playlists with her. I was always there.

But as she grew up, her circle got changed and people she hung out with became...weird. Like, that kind of stereotypical people who are always blabbering about someone's boyfriend or some worthless gossip. They were all super materialistic with their unnecessarily expensive stuff that their parents paid for. My sister slowly became that way.

Although we were comfortable, her "demands" were too much. Like, straight up demanding my father to pay for a $250.000/annual college. We were nowhere near that. She started asking for a car, some expensive designer brands like Gucci or Balenciaga. She doesn't read books or research anything. She listens to objectively bad, ghetto music with no taste. She dates "bad boys", constantly talks about other people's lives, I mean, CONSTANTLY. 24/7. I can't sleep because of her yelling gossip coming through the walls.

She didn't get to go to that $250.000 college, but she still went for a really expensive one just for the sake of it, which my dad paid and then she dropped out on her 2nd year. She has no skill or passion she could build upon, she just did it because she knew my dad was there.

Then, of course, my dad hired her in his own business and gave her a senior wage for her zero experience and knowledge.

I'm currently employed at one of the biggest tech companies in the world. I'm a known expert in my area with a dozen different skillsets in various areas that I can earn money from. He pays her nearly as much as I get paid.

All of this while she treats them like dogs. She yells at my mom and dad for the stupidest of things. She asks for my dad's car and if he genuinely says "the fuel is low, I gotta use it sparingly for the whole week" and doesn't give it, she starts yelling and crying. Which, of course ends up with her getting the car and emptying the tank.

They're paying $800 for rent, but driving a $2000 leased car. When I asked my dad "how are you doing financially right now" a couple of months ago, he said they were living to make ends meet. But they just bought her a brand new iPhone. She bought a new iPad and went for a vacation abroad for 2 weeks in the middle of the winter.

Again, all of this while she doesn't have the slightest respect for them, nor me.

She yells at me when I'm with my girlfriend, causes inconveniences about everything, takes my stuff, and then paints me as the bad guy to my parents.

4 months ago, things went really bad when I wanted to get the car to take my girlfriend out for a date. They knew I was going to go out and had planned a night, but she still took the car without asking and my plans got messed up. This happened many times before. When I said "why aren't you as strict on her as you're on me?" to my parents, they got mad and blamed me for "always" starting a fight. I couldn't believe it.

I've been avoiding my sister and dad for the past 4 months. I didn't talk a single word with them. I just go to work and come back to sleep. I'm only talking with my mom because they're bullying her and I don't want to leave her alone.

I was also looking for a reasonable place to move out, because I'm done with them. I don't care anymore. But economy is genuinely at an all time bad and even tho I make good money, I can't afford rent for a place without giving up 60% of my income and my marriage plans, because the rents are CRAZY here.

This morning, I got up to go to work. My sister was taking a shower in the bathroom, so I asked my mom if there's any spare toothbrushes. She said "I'll get yours from the bathroom" and went in. My sister started yelling "why is that idiot's stuff is here" and blah blah. I didn't respond, I just listened to her insults. I went to brush my teeth but she kept going and I finally lost it.

She got in her room and I hit her door. I yelled "I'm going to beat you if you come out". I never put my hands on her in my entire life. But I couldn't take it anymore. She started crying and called the police. She said that I threatened to kill her and "she feels threatened for her life". They came and took us. She pressed charges by taking advantage of the "women's statement is prior" law in my country and ruined my pristine criminal record. She ruined my life.

And my parents still stood by her side. I can't believe it. I saw betrayal from everyone in everywhere. From my friends, significant others, colleagues, anything and anyone you can think of. I couldn't believe seeing betrayal from my own family too. I can't wrap my head around how they could not see the situation they're in. I can't believe how they could be willing to push me away like this. I was nothing but a good son.

Anyway, am I the asshole in this story? Is there something I'm missing? I genuinely can't see if I'm missing something. Please, I need to hear other people's opinions on this.

Thank you for reading, I really, really, REALLY needed to get this out.

TL;DR:
My (26M) extremely materialistic and disrespectful sister (22F) is using my parents for money and today she ruined my life by calling the police on me because I said "I'm going to beat you if you come out". My parents stood by her. AITA?
