Unit support costs are costing you 28gpt - I'm guessing that you have two defenders in each town; that is completely unnecessary in towns that are not vulnerable to the AI, ie those deep within your territory. Also, your towns are too small - once you get them above size six, they will give you three free unit support, further reducing your expenses.
Berlin and Hamburg would fare better building an aquaduct; Konigsberg and Leipzig are building colesseums, probably the least useful of any building.
