I think that's a bit disingenuous really - the Tories are justifying everything they are doing atm by saying 'But Labour don't have a plan...'. The role of the opposition is to hold the Government to account, and if they actually thought spending was too high, they should not have promised to match it. And if they said that 'just to get into power' then they are liars. (Well, we know that anyway by how they have abandoned their manifestos).
The debt/deficit does need to be tackled, but it is not as unusual historically as the Tories would make out, and reducing it more slowly and allowing more economic growth to help ease the burden is a perfectly rational and accepted way of approaching it (taking the Keynes approach). But it is being used in order to tackle all sorts of idealogical things, that frankly are not essential to deficit reduction. And if the cuts tip us back into recession, as I said earlier - guess what - the deficit and debt get WORSE. Tax revenues go down, benefits payments go up, unemployment goes up, homelessness goes up, investment goes down....
They also need to be fair and be seen to be fair. Atm they are grossly unfair. The Child benefit is a good example of that - policy is rushed out, and massive anomalies are left in. That cut is going to really hit us - we lose 10% of our income. Meanwhile familes on about DOUBLE what we earn keep it. Madness. It doesn't even save that much money, and goes against the basic principle of taxation, whereby partners do not have to disclose their financial affairs to each other (that is why couples are taxed individually).
The Government might pull it off. Might. The rich are not yet going to be hit, it is the poor and middle income households who are bearing the brunt of this. The rich won't notice. I hope that the 21 millionaires in the cabinet however will adopt a more flexible stance over the cuts, as if we get another quarter of economic contraction, then they MUST adopt a plan B, or we really will be emulating that 'shining example' of Ireland.
