I remember before the current tax credits (Blair gave tax credits to parents earning up to £60k although I never got any). Family credit came in in 1986 when I was working first with small children but we never got it.
It was family income supplement that was around when I first started working. FIS was means tested and introduced ni 1970. I never got that either. It got you free school meals and payments (and was brought in by the way by the Tories - Edward Heath). There was also family allowance from about 1945. That was before Child Benefit. My father always called it family allowance not child benefit as that was the terminology of his day.
"Over the 1930s, growing evidence showed that large numbers of children were born into poverty, with 47% suffering five years or more of malnutrition. Higher wages would not effectively target these children, as the majority of male workers had no dependent children. A White Paper of Family Allowances was published in May 1942, giving costings for various levels of family allowance. These were not immediately adopted, and following the publication of the Beveridge Report, which called for subsistence levels of payments, uprated with the cost of living, the Family Allowances Act 1945 was passed. This provide for a five shilling per week payment for each child, after the first. This was designed to support large families, and was set well below the nine shilling a week subsistence level (further devalued by inflation) recommended by Beveridge.[3] In 1952 the rate was increased to eight shillings per week. In 1956 the rate for the third and subsequent children was increased to ten shillings per week, and the maximum age for payments for dependent children was increased from 15 to 18.
In 1968 the rates were increased from 8 to 15 and then 18 shillings and from 10 to 17 shillings and then £1 respectively,[4][5] but this was paid for in part by a reduction in the value of child tax allowance, so that the poor would benefit, but the middle classes did not.[6]
In 1975, the rate was increased to £1.50 for each child after the first.[7]"
tax credits have allowed big companies to pay low wages however. So it may be if there were fewer tax credits (and we have very high numbers of people in work and perhaps skill shortages at the moment) and perhaps may be less immigration we might find employers have to put up wages. Perhaps it is fairer that employers pay a higher wage rather than tax payers (many of whom are working mothers) pay high taxes to enable the state to pay tax credits which effectively subsidise minimum wage employers to keep wages low.
