The employment rate is a tad low for facility income, so I'd suggest raising that.
You'll want morale higher and crime lower in order to lower your production costs.
A) To increase ER, build more jobs to compensate for the high flats (planet should have jobs-to-flats ratio of 1.0-2.0 for best income, preferably 1.5.
B) To increase morale, build parks, fountains, statues, hospitals, chapels, churches, temples, cathedrals, palaces, alazhi farms, research centres, computer control centres, conference centres, command centres or government houses.
C) To reduce crime, build civic centres, barracks, prisons, statues, fountains, casinos, crew quarters, council flats, conference centres, command centres, government houses, palaces or holonet communications centres.
(Hint: you could increase morale and reduce crime by building facilities present on both of the lists found on B & C.)
Very few of those facilities will produce income, though, and you'll need to take into account how mass constructing those facilities might affect the employment rate.
