I do use the word "impracticable" about one detailed provision of my scheme, in the event of mass unemployment: namely the proposal that when men had been unemployed for six months, if they still remained unemployed, they should be required to attend at a work or training centre as a condition of getting unemployment benefit. That proposal is easy, if there are only a few thousand or tens of thousands such men: it becomes impracticable if, through mass unemployment, there are hundreds of thousands of such men. But giving up that particular detail of the scheme would not mean giving up the whole scheme. I myself have made suggestions for adjusting the scheme in respect of this detail, if the amount of prolonged unemployment is excessive.
