Why can't I unlock the Bureau of Bureaucracy?

This page gives three alternatives, I'll expand on them where necessary:

1. Fund all education and health buildings to their maximums for several months.
   Make sure none of those building are currently used over their maximum capacity and that you have enough money in reserve to pay for this before you attempt it.
2. Unlock the building through a U-Drive-it mission. (Requires Rush Hour or Deluxe.)
   The associated mission is "Mayor's Got New Socks!", a news van mission. You need a television studio and a mayor's house to be able to play this mission.
3. Cheat. Press CTRL+X to open the cheat box and type "you don't deserve it"
   This will unlock all buildings. There's no way to undo this.

Option 1 worked for me.
