* A sentence with comparison structure

[soundok]

Florida will gain another quarter-million jobs this year alone, many of them in such high-paying fields as electronics and banking, making the state's economy far more diversified than it was ten years ago.

I think this sentence is structured with objective complement comparison. So, "than it was ten years ago" should be "than it ten years ago." I do not know "was" compared with what before "than".
