"Family allowance was introduced to encourage people to have children after the war
Wecwereherefirst- great point! If your grandmother's family survived with 21 children, WITHOUT benefits, then why do we need them now?"
Here is a small lesson in Social Policy.
Rowntree discovered that the WC couldn't earn enough to adequately live, money was being made by those at the top, partly because they didn't pay workers enough, so benefits were introduced to alleviate poverty (caused by unfair distribution of wealth).
Family allowance was introduced to keep people out of hospitals/workhouses and institutions that cost more than throwing a pittance at families.
When the blue print for the Welfare State was put together, it was realised that if people didn't have enough food then they would clogg up the hospitals, so we had to have a comprehensive system of welfare.
We couldn't have child laws that state the care that children must have, unless "we" (Government) ensure families have enough to live on.
Either that or they would have to tell the truth about how and why wealth is distributed.
