Ask yourself WHY should UCLA help you? It’s a PUBLIC university, not a private one. It’s mission is to serve the residents of CA. You have no ties to the state. Your parents are neither voters nor taxpayers. CA isn’t hurting for talented instate students, that requires it to offer financial incentives for recruiting OOS talent the way AL or MS does.
If you can’t afford the OOS cost, then pick another school. It’s not like there aren’t literally thousands of other colleges in the US, including many CA private colleges which offer generous FA.
