Just looked at 2013 accounts for dulwich college, ?1.9m total value of bursaries. Taking the other schools into account, I think it is safe to assume that almost all the dulwich estate income goes on bursaries. As for the toy shop, rents go up, it's a fact of business - and from what I can see the rise is not unreasonable. My wife has a small office from the crown estate, rent goes up 20-30% every 3 years on renewal. Personally, I think a small toy shop is going to have a very hard time surviving with the online competition.
