Wealth is a complex thing in Democracy 3. far more so than before. I’ve been wrestling with bugs in it today which have reminded me how intricate the new income simulation is. How does it work? Well here is a rough synopsis.

Every sim voter in the world (defaults to 2,000 of them) has an ‘innate income’ which dictates basically where on a scale of 0 to 1, they sit on the big income spread. This is their best effort, in an unchanging world, to make money. If you implemented no policies, they had no characteristics, and the world was unchanging, this would be their level of income. Obviously the real world is more complex. The simulated voter is actually a fractional member of a whole bunch (maybe 5 to 8) different voter ‘groups’. For example, to keep it simple lets say the voter is 52% motorist and 33% parent. That might sound weird, but this just makes him an average car user, who maybe has teenage children, so not a ‘hardcore’ parent with multiple infants.

Now the player may have policies in place, or simulation values may exist in the world that affect income for the groups in which the voter is a member. For example, Child benefit may make parents better off, whereas Petrol tax may make motorists worse off.  Because our voter is a member of these groups, we run the equations and work out the combined effect on their final income based on these changes.

But it’s not that simple… because we also have policies, situations etc which affect people based on their income. For example income taxes affecting the middle classes, or luxury goods taxes affecting the wealthy. The real complexity hits where someone may be middle-income by default, but the taxes levied on them due to their middle-incomeness actually makes them poor. With me so far?

What this means is that the income calculation has to essentially do this:

Step #1: Work out the extent to which we are poor, middle income or wealthy, based on our innate-income. Using this data, calculate the effects of the policies that affect those 3 groups on our actual income

Step #2: Calculate the effects of all the other groups, such as being a farmer, motorist etc, have on our income, to come up with a final figure for our new ‘adjusted’ income.

Step #3: Given the final income figure, place us in the poor, middle income or wealthy group accordingly, which *may* differ from our membership in step #1.

Why all this grief? Because it is possible, through social engineering to take people whose basic income would be poor, and raise them 9through state benefits) to be middle income, and then reap the benefits of their membership in that social group. For example, middle-income members may get a kick out of seeing a certain cabinet minister in office who sympathizes with them as a group (they like the speeches he/she makes…). This can work, despite the effect that only government policy has put them in that situation in the first place.

It’s a difficult effect to describe, but it’s a real one.  Peoples final income differs from their earned income dramatically due to state policies, and you tend to ‘identify’ with the political view of the income group you are ‘effectively’ in. In other words, you base your views on your take-home pay, not your headline salary.

I’m definitely going to make a simple pong clone one day…

Sooo.. I found myself almost sleepwalking into adding a new feature to Democracy 3. I honestly can’t remember actually making the decision to include it, it just seemed to ‘happen’. In democracy 2, the model for income of voters is fairly basic. You can implement policies which affect different levels of income (luxury goods tax hits the rich, for example), and that would affect the membership of the poor, middle income and wealthy voter groups. So far so good.

But it turns out that life is more complex than that. My example of choice is ‘agriculture subsidies’. In the current game, Agriculture subsidies make farmers happy, and they also encourage people to become farmers (so farmer voter group membership rises). This is accurate, and logical and works well. But it has no actual effect on anybodies personal income. This is clearly wrong. So in Democracy 3, I’ve changed things so that each voter group has an ‘income’ value, and policies (and events) can feed directly into them. You also get an extra tab on the graph, and list of effects to see these things happening.

So now… Agriculture subsidies have their usual effects, but also they make farmers wealthier. The subtle effect is to push farmers out of poverty, and towards wealth. This may be more logical, and detailed and accurate, but why is it good game design? what does it add?

let’s say you have identified the poor, and farmers as two ‘core’ groups that you will base your support on. They are the bedrock of your voting block, and you will keep them happy. So far so good. One of your policies, as demanded by your poor farming supporters, is higher agriculture subsidies, and so you do their bidding. One of the side effects is now that a chunk of those poor farmers are now not so poor. They start joining the middle income or even wealthy groups, and that brings with it a host of other influences to their thinking (voters are in multiple groups, at varying strengths). Suddenly, there are more farmers thinking ‘hold on, I don’t think I appreciate this luxury goods tax, or inheritance tax. What were you thinking???’. Your policies that subsidized the poor and hit the rich (including those taxes on the rich you levied to pay for the subsidies) are now inadvertently affected the very voters you were trying to help…

it’s a subtle effect, but I think it’s real-world, and also represents an interesting trade off. I see this in British politics a lot. The left were concerned about child poverty and pensioner poverty, so to combat it, we got better provision of child benefit and winter fuel benefits for the elderly. Worthy goals, but they also push up the living standards of parents and the retired. This has side effects. Now, in a time of austerity, the government finds it extremely hard to reduce either benefit. This is the problem of so called ‘middle-class’ benefits. A policy designed to do one thing has had other effects, due to the changes on people’s income.

I think this is an effect worth modeling, and it’s fascinating to see it in game. When trying to make environmentalists happy, all my feed-in-tariffs and grants also make them better off, and suddenly I’m the champion of the wealthy and not the poor. I love trade-offs and compromises like that. They are the key to what makes Democracy interesting to play.
