The Davey family's ?815-a-week state handouts pay for a four-bedroom home, top-of-the-range mod cons and two vehicles including a Mercedes people carrier.
Father-of-seven Peter gave up work because he could make more living on benefits.
Yet he and his wife Claire are still not happy with their lot.
With an eighth child on the way, they are demanding a bigger house, courtesy of the taxpayer.
More on the way: The Davey family at home.
'It's really hard,' said Mrs Davey, 29, who is seven months' pregnant. 'We can't afford holidays and I don't want my kids living on a council estate and struggling like I have.
'The price of living is going up but benefits are going down. My carer's allowance is only going up by 80p this year and petrol is so expensive now, I'm worried how we'll cope.
'We're still waiting for somewhere bigger.'
Mrs Davey has never had a full-time job while her 35-year-old husband gave up his post in administration nine years ago after realising they would be better off living on the state.
At their semi on the Isle of Anglesey, the family have a 42in flatscreen television in the living room with Sky TV at ?50 a month, a Wii games console, three Nintendo DS machines and a computer - not to mention four mobile phones.
With their income of more than ?42,000 a year, they run an 11-seater minibus and the seven-seat automatic Mercedes.
But according to the Daveys they have nothing to be thankful for.
'It doesn't bother me that taxpayers are paying for me to have a large family,' added Mrs Davey.
'We couldn't afford to care for our children without benefits, but as long as they have everything they need, I don't think I'm selfish.
'Most of the parents at our kids' school are on benefits.'
She added: 'I don't feel bad about being subsidised by people who are working. I'm just working with the system that's there.
'If the government wants to give me money, I'm happy to take it. We get what we're entitled to. I don't put in anything because I don't pay taxes, but if I could work I would.'
The couple met in a pub 13 years ago. A year later, at the age of 17, Mrs Davey gave birth to Jessica, now 12.
She was followed by Jade, ten, Jamie-Anne, eight, Harriet, six, Adele, four, the couple's only son Tie, three, and Mercedes, two.
'It cost too much to carrying on working as we were actually better off unemployed,' said Mr Davey.
In addition to income support, housing benefit, child tax credits and a council tax discount, the couple receive carer's allowance and disability living allowance for Tie, who suffers from a severe skin disorder.
Despite filing for bankruptcy 18 months ago after racking up ?20,000 of debt on mail order catalogues they still insist on splashing out on four presents per child at birthdays and last Christmas spent ?2,000 on gifts alone.
'Santa is always generous in our house,' said Mrs Davey, who once applied to join the police but was turned down.
She insists her husband would do any job 'as long as we could still afford the lifestyle we have now'.
Mrs Davey, who spends ?160 a week at Tesco, says she does not intend to stop at eight children. Her target is 14.
And she adds: 'I've always wanted a big family - no one can tell me how many kids I can have whether I'm working or not.'
