My beef with benefits is the way they are distributed. I'd happily have the benefits bill be much higher but be administered more sensibly.
JSA is not enough for most people to live on when they have been made redundant, especially if they have lost a well paid job and have a lifestyle that matches their income.
Disabled people don't get anywhere near enough financial support, and when people are genuinely too disabled to work, benefits should be enough that they can actually live a life, not just exist while still having to forgo things they have real medical need for. Benefits for people who have terminal illnesses are not enough.
Carers allowance is sickeningly low, and should be much more. Widows and widowers should be better supported as well.
Child tax credits are too high. We should not be paying for people to choose to have children they cannot afford, and I don't think any benefits should be given for more than two children, including housing benefit entitlement. If parents with more than two children become ill, disabled, or are made redundant after having children, then they should have their safety net in the form of more generous disability benefits and JSA. I'd rather see people get free childcare than income support so they can go back to work after mat leave. We should be taking more action against parents who don't pay for their children instead of allowing them to be secure in the knowledge that someone else will pay for their children. If people can't pay for their children right at the time that their children need to be paid for, then they should have a sort of loan thing going on with the government so that their children are supported, but they are expected to pay it back, otherwise they face criminal charges and shouldn't be allowed passports and driving licences.
FSMs and the pupil premium are a joke. They don't reach the people that need them but are still sometimes wasted on people that don't need them. That whole thing needs a serious re think.
Basically the benefits system should, IMO, be a very safe and secure safety net that is able to fully provide for people who are in need, but people should know that it is only an safety net, and they are expected to provide for themselves and their children if they are heathy enough.
