But it's excellent for Government statistics. Both parents work and farm offspring out to a childminder results in 3 people classed as employed and paying tax. One parent works, other stays at home to bring up the offspring results in only one person employed and paying tax and Government paying unemployment benefit to people who might otherwise have been employed as childminders.
Now if Government really cared about family values they'd pay a childminding allowance to people where one parent looked after their own children full time instead of going out to work.
