AITAH for telling someone they are setting up their life for failure

A friend of mine has nothing going on for her life. She is 29 years of age and has been heavily dependent on her parents to provide. Yes , even up until this age the parents provide for everything. She seems to think that she is just openly entitled to everything. She has also never worked a day in her life. Does not have much social/people or real world skills. She has siblings who were brought up differently and did not have much assistance or dependability from the same parents. The siblings have moved out and have well established careers. Not sure why the parents treat her differently?

She is also still in college and I feel like she is just wasting her time and parent’s money on taking bogus courses/programs that she doesn’t finish.

I have offered numerous times to help her get a job but when I did. She would always come up with a reason to quit or employer would “lay off” (basically always blaming the employer). She has not held a job anywhere for more than 30 days.

I didn’t want to offend her but I made some jokes about her being in college at age 40 without having any skills. She seemed to get very offended and got angry at me. I told her it was reality because she is turning 30 soon and has not changed her life since I have known her (middle school/high school).

Maybe I just care too much. The parents should be the first to blame?
