I don’t think the schools make much of a difference in terms of employment opportunities. I’ve got one kid who finished his undergrad at a CSU and another who completed her education at an elite private. Both kids have the same majors. Both went on to grad school for identical master’s degrees - one public, one private. The really big difference in terms of outcomes down the line is that the kid who opted for private school is carrying a lot more debt.
The kid at the private college got a job relevant to her major immediately after she graduated, as did the kid at the public. The pay at those first jobs was roughly equivalent. Neither got their jobs via campus employment or recruiting – though my DD certainly got a lot of support from her private college career center, but she found the job on her own, through public listings – as did my son. And they got their jobs by virtue of the experience they brought with them (work, internships, etc.) – employers really care a lot more about background and experience than they do about the name of the school.
If you were looking at an elite like Stanford or Yale a case could probably be made – but you are still waiting to hear from UC’s and it’s pretty likely that your daughter is going to be admitted to one. Santa Clara and Loyola are wonderful schools, but there is no employer that is going to place greater value on those degrees than a degree from any UC.
I do think that the quality and rigor of my daughter’s education at the private college was definitely better than my son’s CSU – but we weren’t paying full tuition, and I don’t think that it was worth the price differential between full tuition costs at both.
I think you need to wait until all results are in and see where your daughter’s preferences are at that point, and if she wants the private schools, explore her reasons. But the job thing is simply not true - it just isn’t going to make any difference at all. (Other than serendipitous reasons – wherever she goes, your daughter may meet someone who knows someone who knows of a job opening at such-and-such a company, and that turns out to be how she gets the job --but that can happen anywhere, and it is also just as likely to happen through EC’s and other activities as through the career center.).
In other words – there may very well be good reasons for your family to invest the extra money in the private school, given that you are in a financial position to have that luxury — but future employment prospects isn’t one of them.
