The theory of the Global Justice assumes that the market economy offers chances of fair participation to humankind with a continuing sinking percentage. Through fusions, rationalizations (by robots, CNC, etc), and optimization of computers (hard - & software), this percentage will reach, in the coming centuries, such significant values that for the subsistence of the loosers of the market economy there will be needed resources that are logically to be sought outside the market economy. These resources can, due to the Theory of the Global Justice, only be the same globally as the market economy itself.
The present-day real unemployment has reached in todays industrial nations - under consideration of state employment promotional programs, courses for retraining, other job creations, surplus of public servants, etc. - already an average percentage of 15% to 30%, so that our prognosis of 40% within the next 20 years could be pointed out as realistic. In the poor countries the numbers are even worse today.
Because the keeping and creation of jobs are usually attached to the so called basic conditions of individual nations, the present day ruling governments and parties mutate deliberately to the representatives of the interests of employers. In most cases, nations and power-blocks are contending about an optimization of their basic conditions (tax-breaks, infrastructure, wages and wage-conditions, cooperation with sciences and universities, etc.). At the moment, politicians therefore, only dispose of little counterbalance to the interests of the owners of value creating processes. This is not one of the smallest reasons, why they lose so much confidence from the public, at the moment.
The financing of the necessary minimal global planned economy can be risen without endangering an optimal market economy from a global grip to the inheritance of those, that profit from an increasingly globalizing market economy mainly for generations, in a disproportionate degree (often without any own performances).
