OK. So let’s say society has 100 people in it, but only 50 are employed.
The others have no income (they are too young or old or incapacitated to work, or they are an unpaid carer of those who cannot work, or they lack the knowledge and skills required by the market).
Let say the 50 who are employed can produce all they need for themselves AND for the other 50.
How do you suggest that the market works to provide for the other 50?
