You are missing one vital thing - lending to the general public. The labour government has built the last 10 years on us borrowing and fuelling the economy through more and more borrowng. There is a three-fold assault on this, right throughout the range from the government downwards.
Firstly, the government (through the FSA) have tightened up regulatory compliance to the point where nobody wants to lend for fear of falling foul of the regulator. This has massively reduced the appetite for lending and it not happening. As a codicil to that, there are a pile of shark companies popping up threatening to sue left, right and centre for any lending that has been done, regardless of how well that lending was conducted.
Secondly, you have businesses who are tightening up their credit lines, to the general public and between each other. Much highstreet expansion has been built on credit - store cards, credit cards etc - and this is not available anymore. We aren't going to see that level of available credit for some time so people are going to spend MUCH less. The impact of a 2.5% lowering of VAT will not make up for the loss of £1000's per head of credit lines.
Finally you have have the individuals themselves. They are either scared witless by the media and what seeing their friends being made unemployed, borrowed to the hilt and staring at an IVA or both. Even if they could get credit, they are terrified of the consequences.
If anyone thinks there is going to be a quick-fix or a bodge to sort this out, they are wrong. House prices need to settle, peoples credit needs to settle and confidence needs to be restored. You can't wave a magic wand, tell people that stuff will be cheaper and expect to come out of a recession. The labour government has been about headlines and no substance and this is one more example tbh.
Whilst much of this is true, I beleive the end-game is different. GB & AD have explicitly said that the the PBRT will set out a mid-long term plan of how the Treasury is going to pay for this. They will tell us today of deferred tax increases, they will tell us today of deferred reductions in public spending.
I beleive there are only two options available to HMG today.
Option 1
Do nothing. Let spending drop, let business close, let deflation set in, which will cause spending to drop even further (why buy a TV now if it will be cheaper in a few months?) Job losses, home reposetions, people unable to pay debts, banks will have even more bad debt etc etc etc. WHilst this option may actually be good in the very long time, in that it will completely rebalance the economy, long term, the pain it will cause for the next maybe 10 years or so will be unacceptable.
Option 2
Pump BILLIONS of Treasury money into the economy. Liken it to a massive capital and revenue investment in the hope that it will get people spending some money. I think there is an underlying hope that people will also try and reduce their debt where they can. If I use myself as an example, I have approx £10,000 of debt (not including mortgage), but I have approx £20,000 of savings. For the past few years this has worked well for me because the debt has all been at 0% because I played the card companies and did some 0% balance transfer whoring. However, when my last offer expires in May, I will just pay this off in full against my savings.
Personally, I am currently putting as much as possible into savings. I am saving approx £1,000 per month now, compared to £300 a month last year, where my income is around the same. However, the reason I am doing this is because in the next year or two we want to take advantage of the lower house prices and move from our current house to a new house. Ideally I want to keep our current house and let it out, so I know we are going to need £40,000 or £50,000 saved up for a 15% deposit on our next house to get a good mortgage deal. Being a company director with a low salary and high dividends, I know it will be even more important to have a good deposit.
Regarding my business, as I've said we're stockpiling profit in our bank rather than investing it in new staff or withdrawing it as big dividends etc.
Both of these are bad for the short and mid term economy.
As I see it, Option 2 the only option, because doing nothing will cause the economy to fall.
