Cut everything accross the board and make people realise that the state is only here to support the most needy, not the bone-idle, lazy or rich.

Stop IVF funding, as the NHS is here to save lives, not create them.
Make public sector workers pay their fair share pension contributions.
Stop paying child benefit for more than 2 kids (if you can't afford them, don't have them).
Slash Job seekers Allowance and other non-working benefits and force the non workers to do voluntary work to help society, whilst looking for paid employment.
Reform Prisons and make them basic. No more TV's, Pool tables, conjugal visits etc.
VAT on kids clothes and food.
Bring back Hanging, to get rid of persistent and costly prisoners. I'd volunteer to pull the lever and cut them down!

I could go on for ages, but don't want to rant to much, just yet!
