What can i do about my mom?

My mom is a stupid b**ch, no other way to put it. Shes a stay at home mom who does nothing but complains. She literally only works about 2 hours a day doing chores, and sleeps the rest of the time, then complains about how hard she works. And she complains about money, and that she ONLY gets $3000 a month, JUST TO TAKE CARE OF GROCERIES!!!! And then she f**kin says shes living in poverty, and shes drives a brand new BMW, we live in a 3/4 million dollar house (with a paid off mortage), and my dad has a 6 figure job. And earlier this week, she said she wanted a new computer, so my dad bought her a new macbook pro, and then later that night when she got it i hear her complaining about my dad and calling him cheap, and how she deserves better. And im not even going to go into how badly she screwed up my little brother. And i have friends who's parents are struggling to put food on the table, then i go home and hear this c**t complaining about having a mansion, a BMW, a mac, and money at her disposal. And ive tried to tell her that she needs to be more appreciative, and then she basically says "appreciative of what?". Is there anything i can do to make this worthless hag less b**chy and selfish?
