<prompt> Human: My sister is about to start Grad school, she decided to go to a university out of state while her twin decided to stay in state to save more money. So basically she thought that she would be fine with living with debt, but now she is about to start grad school, and she even wants a PhD but she already has over 50k in loans. She constantly spends money on stuff she doesnt need but refuses to stop. My dad also helps her out A LOT not tuition but stuff like rent and food, she keeps saying that shell pay him back.Im 2 years younger than she is, Im a US Marine so I never had to use my college fund, and Ive always been pretty good at saving money. Currently I have about 60k in my savings, I barely spend anything. The one thing I spend money on is my car. I love cars, currently I drive a 2014 Challenger and I always am competing with my dad about who has more hp. My sister however has like a 2002 ford focus thats completely beat up. So a few days ago I was at home and my sister was there too, while watching TV I mentioned to him that Im planning on trading in my challenger for the new 2016 Camaro when it comes out. We started up our normal competitive talk, he said he would have to get something new too, when my sister heard us talking about freely spending our money she had a breakdown. I didnt know how much debt she had but I did know she had a fair amount. I realize now that I shouldnt have started speaking about having tons of money when she is in the opposite position.So then later my dad explained to me about her situation, how much debt she has and all that stuff. My other sister then said something to me about paying off her debt for her. This is where I need the advise. My opinion is that she got herself into that mess, but I still feel bad for her. However I still see the fact she wastes a fair amount of money. I feel that if I did give her money to pay off her debt then she would just go back into the same situation. Im fairly sure my income is enough to simply pay for her school though too. I have a good job that I know will translate very well into a civilian job, where Ill easily be able to make 100k, and atm I dont really have anything to spend my money on. So if I did help her I probably wouldnt have any issues. Most likely she would never pay me back, though she would say that she will. So do I help her? And if I do how much should I help her? If I do help her then Im still not going to do enough to where I cant get what I want, so it wouldnt really be any different for me except my savings would be smaller. Ive offered to pay for some things for her in the past, but she always says no. So if I should help her then should I go around her? Im thinking I would try to convince her, but then Id go around her if needed. Id rather have her be angry at me then fail at life.Edit: I exaggerated how much she spends on useless things. She does a lot but her debt is still like 95 student loans. Also forgot to mention that she is in psychology.  <response>: DO.NOT.PAY.HER.DEBT The only thing this will teach her is that she can run to others and they will bail her out, she made her bed, she was warned.
