Your finances are not balanced. You have a shortage on your monthly balance of payments. You should either decrease your costs or increase your income but at the end you must balance the monthly income and cost or your debt will increase. Income can be increased by building more corporations that are working at full capacity and are upgraded to high quality and high efficiency. These corporations will produce more profit and pay more taxes. You can also increase corporate tax but that will reduce their profitability and market value. Cost reduction can be achieved by deactivating some of your weapons to reduce the cost of the army or a reduction in social security. Education and health can also be reduced but rebuilding education and health is a long process.
