By finding out the accepted relation between the average (lower) income and the level of social welfare (poverty line) according to step 2 it is possible to determine - at least qualitative - the critical level of the employment rate below which the social cohesion of the society is in danger.
That this critical point is achieved within the next years is getting obvious by looking back at step 1:
It is the case if there is an intersection of the critical employment rate (step 3, part B) and the employment rate which is caused by the increasing unemployment rate (step 1, part B). The worst case takes place under these circumstances. Without an intersection of both lines the social cohesion might not be affected. But this should not be connected with a licence for political passivity.
How can this critical point be avoided?
Consequently the only solution to avoid the worst case of a social breakdown is the increase of the employment rate by reducing the unemployment rate. But the decrease of the unemployment can - as shown in chapter 3 - only be achieved by reducing the hours worked.
