In all likelihood you need to index your foreign keys, and possibly other fields, but as you haven't provided table and index definitions it is hard to say for sure. Idepeing on how many rows are hidden I'm not sure an unqualified query on this view can run in 1/60th the time even with indexes present - the sequential scans are efficient if the proportion of the tables being returned is high.
