The systems a joke and it has been for years. An old girlfriend, sort of, was a single parent and she got all sorts!
Rent paid, some kind of tax credits, child benefit, and other assorted payments, in all she got about £1300 a month in benefits alone plus she had a part time job of 16 hours a week which brought in about £500 extra. I worked full time and took home about £700 less than her
If you want a kid, you should be made to prove you can pay for it
