You can also get a loan by left clicking, and pay off debt by right clicking the debt resource on the right of air experience. You gain debt by going below 0 in your treasury, this mostly happens if you have a negative daily income or changed your Economy Growth Rate. You can find this under your Political Window in Laws, the better it is the more Tax income you get, it also increases Stability slightly and increases Construction Speed although you’ll have to pay a bunch of cash to change it, even if it gets changed via event. Unfortunately the tooltip won’t tell you how much you’d gain by changing the law. You can Find these under your Political Window in Laws, each Grant you some bonus while costing Money or sometimes even other things, you can reduce these by changing the law at the cost of PP, doing this will reduce your daily expenditure but also lower your Ruling Party Popularity. You can also just gather as many IV points as possible and gain a daily income boost from it You can sell off 1 IV point to gain 0.95 Cash if you really need it.
