And as for whether Anita's family is 'educated and wealthy' as asked--
the Netherlands is a country where almost everyone you'd bump into is very well educated. Universities are pretty much accessible to anyone, (if you have earned the appropriate grades in high school that are required to qualify for college/university.
And as for whether her family's wealthy...as a whole, the Netherlands is one of the wealthiest nations in the world, but individually, you'd find that most Dutch citizens would qualify as decidedly "middle class" even the ones that can boast high salaries! One reason is the high tax rate in that country, but that would be another thread, or even forum, entirely....
(ha unless we'd do the thread "which royals pay taxes" or sth like that
So if I'd have to bet, I'd say Anita's probably from a middle class background, like most Dutch citizens. But then again, I don't know anything about her family background, except that I read somewhere that she lost a sibling way back when..
