Income

Overview
Income is an attribute of a planet that produces approximately that amount of wealth per round to the organization with which that planet is affiliated. Income of planets in rebellion or planets that were captured in the previous round is often inaccessible to an organization.

Calculation
The amount of wealth an organization gains every round is calculated as follows:

WEALTH = (INCOME* - LOST MORALE) x INFRASTRUCTURE x TECH + TRADE DEALS +/- RANDOM

where LOST MORALE is a penalty for having near zero negative morale, INFRASTRUCTURE is the income multiplier based on the amount of money invested in infrastructure since the beginning of the game, TECH is any income bonuses given to you by technology and TRADE DEALS are income bonuses from being in trade deals.

The wealth you earn per round also has a small random component that may influence how much wealth you recieve.

Spies can also siphon some of the wealth you should have received in income.
