Agree re cutting the health in pregnancy grant.
Get rid of free bus travel for school age children (which I assume is supplemented by the public purse?) Set a flat rate of 10p/20p per journey.
Get rid of free prescriptions. Set a flat rate of 50p per item or similar. Exemptions could still be given for specific life saving medication which people are dependent on. The current system of exemption certificates mean that patients don't have to pay for any medications.
Establish what the average age of first time home ownership/rental is. Anyone under that age should not be entitled to social housing, irrespective of whether or not they have babies.
CTC/WTC costs money to administrate. If they sort out the tax system to make it fairer, these could either be abolished or people who fit the criteria could be automatically entitled to it, saving money on processing applications.
I'd table the suggestion of cutting all public sector pay by 5% or similar. Most people would (reluctantly) accept less money in favour of losing their jobs altogether.
Placing a cap on the amount by which house prices can increase (say, in line with inflation) would help people get on the property ladder, saving money spent on HB/social housing and generating more revenue in tax.
Fundamentally, driving down the cost of living in this country would help everyone.
Put up VAT - it has to happen.
Means test CB, but keep CTF facility - the tax free allowance would help parents saving for their future, although I accept that the CTF grant will have to end.
Set a timetable for the banks to repay us and penalise them if they fail - the same way they do to us.
