I’m not familiar with CA (other than various vacation travel throughout the state), but it seems to me to be a HCOL state, so you really would expect a family of four earning 70K when their oldest goes to college (meaning probably not likely earlier in their lives) to have 100K in assets and have saved up 24K for college? Or would counsel them to take out that much in loans for college for just one of their offspring?
CC would be an option, but other than that, our advice to the parents and expectations from them would differ.
Then too, 50% of the folks there earn less than the median. How do they afford it? CA might be good with college tuition as are some other states. Other states are not. We have kids working in our high school to put food on the table for their families. Some also pay the rent (no asset building up there). They tend not to be our stellar students able to get into tippy top schools, but they can be “good enough” to get state school acceptances. If what they are earning is helping to pay for basics, how can that same money be applied to college expenses? Loans you say?
Most move on to the work force - no shame in that - but when one would prefer a college education and fits the profile of being able to do it, it would be nice if there were decent access across the economic classes. The tippy top academically can often find something affordable, but the “masses” have far more difficulty IRL.
