AITAH younger brothers free ride

AITAH For being pissed at my mother? Found out she has fully paid my younger brother's 50k education and paying his bills while paying my (31m) 5k trade program, charging me rent and making me sign over my left over education money (6k). My mother has also intercepted a vehicle that was to be gifted to me by family and sold it before I ever found out, had me help her on a large project which she promptly sold for a lot of money which she used on herself and paying for my brother's education...

I have been working and saving since I was 12yrs old, and was able to buy a house and establish a small but successful trades business. Getting here was not easy, i lived on rice/noodles and wild game because I was broke, went thru a nasty divorce, built my shop out of scrap metal, never once did I get an offer to help.

I don't want any money from her, she's told me she doesn't have any but I would like her to acknowledge that she hasn't treated us equally. I have brought up all this with her before and she feels everything is fair and she has by no means treated us unequally... it's like she's completely blind to it!
