Well civ jewelers alone is worth ~10g per city, give or take. Being the peacemonger i am i dont know what colonial expenses are like, but i doubt it can be as bad as losing the corps money.
Thats really the only corps i care about by the way. Mining inc cant coexist with it and creative is not impressive enough to bother with, and i typically dont need sids to get my cities to size 20, health is usually a bigger concern so i tend to favor enviro.
