Economic Formula

      All resources are given a Terra value. The resources produced globally are tallied on a regular basis. The total Terra value of the earth's resources is then divided by the number of people on earth. Each person then receives their percentage of the overall resources in Terras. I.D.R.A.A. cards' balances are constantly fluctuating according to global resource availability, production costs etc. Limits are set, where necessary, on the amount of any one particular item that an individual may purchase with their Terras, to prevent shortages of resources, with particular regard given to ensuring that basic necessities are always available to all.
