Why is that?

Perhaps these parents feel their kids can get a better education elsewhere.

Which could be true. I don't know Seattle's situation, so can't really comment on that specifically. There could be (and probably are) a lot of factors. A quick check says you don't have vouchers, so that is good. It also says you have some sort of program for "free" community college (also good). Without doing a lot more research into it, it isn't obvious what the problem(s) could be.
