I agree with you there, the state pays people to become parents when they are not emotionally, economically, socially ready nor mature enough to start families. Cancel child benefits and housing for all children born 9 months from now, that will change that.
I'd go further. Cancel subsidised Child Care, so that mothers stay at home and bring up their own children to be well behaved, sociable and good mannered. Rather than farming them out at the first opportunity, at the taxpayers expense, so they can go back to work, and then blaming 'the system' when they turn out to be little monsters.
Then people would only have children when they want and can afford them, and it would free jobs up for people who need them.
Parents need to take responsibility for their own children. The second car on the driveway is not important. The child is.
