The difference with Britain was that in Germany in 1939 25 % of the active people were working in the agriculture sector (afaics in Britain 6 %)=some 4.9 million men and 4 million women .The reason was that the German farms were smaller than those in Britain,which made mechanisation difficult and that the women were working on the farm and the men in the town(the farm was to small to give a living to the whole family).There was a solution:a compulsory merger of the small farms,but the regime was that wise not to think about it,it would cause a mass peasant rebellion,and the state never could win from the peasants .
In 1895 8.3 milion Germans were working in the agriculture,in 1939 8.9 million,the biggest part were the so-called "mithilfende familienangestellte",which were mainly women (wife,mother,daughter) who were working on the farm without receiving wages.
Before the war,the situation became critical because the young women refused to be the slave of the men:they were tied to the farm,could not marry,...They were leaving the farm for an independent living in the city and the regime was obliged to call up female school graduates to fill the holes .
