Privat or professional use of resouces is an irrelevant question. This takes out the basis for all methods to determine the wins. Taxation only for the usage of resources.
The determination of wins, the division in professional and private expenses created a system of madness, the child or career question, because the nanny became uneffordable expensive as a private expense.
The system of madness brought the children per woman quote down to 1,2.
On the half way at the transition towards resource taxation has the determiniation of wins be terminated, because this requires a division of expenses in professional and private usage.
The finance office has only to be interested in the usage of resources.
