How do I earn wealth?

[Jon Shafer]

From my experience, it only effects your treasury if it's 10 or so. It seems to me that the extra gold is lost to corruption or funding science/luxuries.

All taxation collected is multiplied by 1.5 with a Market.

If a city generates 10 gold, but loses 2 to corruption, at 100% tax the city will generate 8 gold normally, but 8+4 or 12 with a Market. The gold generated by a Market is not affected by corruption - a Market applies its bonus to all normally generated tax income.

If you're only gaining one or two gold per city, you're not going to notice it very much in your treasury individually. But even having 20 cities contributing 1 gold each is going to make a difference. Any corruption comes off before you build anything, so if you see 4 gold being produced in a city, it's still worth building a Marketplace.
