Chemistry aside, my experience is that a family must have a HIGH culture before the child can be truly bilingual.

I guess it depends on how you define "truly".If the kid's exposed to nothing but Spanish at home and nothing but English at school he's likely to gain at least a pretty good (if not very good) command of both languages.

He will seldom be equally proficient in both languages.
