It's totally a gamble. I'm not denying it. I'm just offering a reason why they're doing it fast & deep rather than slowly. Both strategies are logical and it just depends on the sort of person you are I guess which you prefer.
The slower you pay off your debts, the more interest you actually pay and more you end up eventually paying. Oh and bear in mind we're merely talking about the deficit here. In five years we won't have paid a penny off our actual debt yet. Just stemmed the tide of overspending.
About a decade ago, Canada faced a similar problem where their deficit was out of control and on the verge of bankruptcy. They chose a hard & deep cut strategy (aka the bloodbath budget) and eliminated their deficit in 3 years. Sweden had a similar issue too but I can't remember when now. The lessons learned from them is that it's better to just pull the plaster off quick and let it hurt now rather than look to prolong the pain over a decade.
To me those who are wishing for a slower speed are simply living in denial of the scale of the problem. Five years just to stop overspending and you think that's too quick!?!?!
If I went to CCCS tomorrow and told them I'm on the verge of bankruptcy. I've overspending every month and up to my eyes in debt. Would they recommend I reduce my outgoings slowly over the next five years because otherwise my kids would suffer? Or would they recommend something faster and accepting the fact that the kids will be affected?
As for the healthcare, it's not something I've read much about. To me, the NHS is a spiralling monopoly organisation which is out of control. I'm not 100% sure if the new plans will help or not but I'm keeping an open mind on that.
