Why not plenty?
Doesn't plenty mean quite a lot? In my opinion, either "I've heard that jobs are quite a lot there" or "I've heard that jobs are plenty there" makes sense.

As an adjective, plenty cannot stand in the predicate position, but is used with the preposition of as an attributive modifier:

The first is simply an error, either typographical or by the writer; it should read: The gopher is very plentiful on the west side of Mississippi.

As for the second-- One pixel is plenty for pictures-- 'plenty' here seems to me to be a pronoun (for 'plenty of pixels'), but I may be wrong. Maybe another member will express an opinion.
