'So - I'm going to just start with the basics - especially in larger societies, there's - not everyone can do everything for themselves. So it makes sense to have some people who make food, and some people who make clothes, and some people who make furniture, and so on. And one of the problems with this is how do you make sure the clothier has food and furniture, and the farmer has clothing and furniture, and so on. In a small society, that's easy, because the farmer can just trade with the clothier. If people get into larger groups, trading directly gets complicated. There's a lot of ways to try and solve this. The - sort of normal way here, is for the farmer to sell food to a person who specializes in trading, and the trader gives the farmer something everyone agrees is worthwhile, but that doesn't have - actual basic real world value? This used to be things like gold or gemstones, and now it's usually a number that just represents some potential thing you can get. The farmer can then buy clothes from whichever trader, and the clothier can buy food from traders. The thing being traded for goods is money, and income is the amount of money someone earns over a period of time.'
'The other problem that bigger societies need to solve is that not everyone can or should be working. Parents with small children, people with disabilities, students, children, artists who make things of cultural but not monetary worth... And then there's the question of how to make sure they have food, clothing, medicine, and shelter if they can't work, and if there's no one in their family who can care for them. Very large societies like the Empire solve this by just giving everyone money that they can buy things with. That's one kind of basic income. This place we're in solves this by making medicine free, and having systems for getting free shelter and food, plus some controls making sure everyone gets paid what their work is worth.'
