I thnk we need to be careful. After world war 2 men came home from fighting,. there was still rationing and a period of national service and austerity and many homes had been bombed so not an easy time but after that we founded the NHS and conditions started getting better. It was almost like we felt we must reward these returning heroes with a fairer more socialist system and we did so for that brief period things got a bit easier (although not for all - countless women who wante d to keep free nurseries and jobs were shunted back into the home to live with husbands who were virtual strangers and had to turn to gin or worse to keep going).
Go back a bit further and things were not as easy. I was looking up the house my mother was born in (she was born at home) in 1929 yesterday. Her parents rented it. When she was 9 months old and her parents had not even been married for one year her father fell to his death in a work accident - he worked at the shipyards as a plater leaving his widow and the baby to fend for themselves. She obviously had to work and benefits were few in the 1930s. She never of course owned a house and most people did not then.
i agree with Ifalied that tax credits just allow the state to subsiside low wages. In fact the state found that on average people were getting £2k tax credits and paying £1k tax - a pointless money go round so they have increased the single person tax allowance to over £11k which makes sense although you still pay NI from about 7300 a year. However the downside is that lots of people cease to be tax payers so are kind of out of the system, earn but don't pay tax. Mind you the UK only brought income tax temporarily to fund a war and then never abolished it so perhaps it's time for it to go. the Financial Times often runs this argument -that if we move to more automation and need many fewer workers it would be fairer not to tax income but instead assets/capital.
