I am playing at Monarch level as a Commercial civ. I have been running into the huge shields lost to corruption problem like many others.
One early thing I have found to help is rush buying under Despotism. This costs you population points ... population costs food ... food is the only thing not 90% lost in outlying corruption cities.
Further food is pretty abundent in this game. In one city of mine I am rush buying Settlers, thus losing like 3 pop, and it still grows so fast it riots. Since the first two food boxes are only 20 food each, low pop is especially cheap.
With this method I can get a temple, library, and courthouse in cities much faster than the plant-forest-cut-it-down cycle. They stay low in pop size, but since the no-aquaduct cap is a mere 6 anyway, it doesn't matter much.
I have found myself wanting to put off Monarcy so I can continue to rush buy with cheap population points rather than expensive gold!
