Labour announced they would be introducing £14Bn pound worth of cuts, only £2Bn less the coalition. So no matter what party got elected you would be seeing cuts now.
As others have pointed out, the speed of the cuts programme would have differed, but you have fallen wholesale into the numbers trap that many people with a lack of imagination seem to do when confronted with large numbers. It may 'only' be 2 billion pounds in comparison to the coalition's cuts programme, but 2 billion quid is still a fuckton of money.
For a start it would pay the daily wage for a fifth of the world's population for a day.
It's £33 for pretty much every man woman and child in the UK.
It's the entire 6th form education budget for a year
It's the entire surestart budget. With change to spare.
It's 2/3rds of the research councils grant.
It's the entire Northern Ireland Office budget. With change.
It's 9x the child trust fund.
It's nearly all of the winter fuel payments budget.
It's all of the JSA budget. With change.
It's all of the statutory maternity pay budget, with the over 75's tv license subsidy on top.
It's 2/3 of the MOD's operational spending.
It's just shy of 1/3 of the entire policing budget.
It's practically the entire FCO budget.
It's the NHS' entire budget for learning difficulties.
..and so on.
I realise that a lot of the budgets i have quoted above have either been severely curtailed, wiped from existence or royally buttfucked by you lot, however, it's to put into perspective the utter abomination that you are a party to and willing participant of.
Yes, the other parties (including yours) during the election were all warning of cuts, but the fact remains that the tories' programme was by far and away the harshest on the table. Everyone knew during the election that labour would lose due to many issues over the preceding years and thus many voted for your lot in the mistaken belief that "you" would act as a brake on the worst excesses of cameron et al.
Clegg and co proved just how mendacious, venal, cowardly and self-serving they were once in power, despite the hopes to the contrary of those who voted for them. Many people swallowed the lies little nicky spouted to the electorate. It wont happen again.
