The problem is that inflation is "set" at 2%.
So each and every year, there needs to be a minimum increase in tax of 2% just to keep services at the same level. It doesn't really matter wether the tax is raised directly through increases (which they don't admit to) or by fiscal drag. We, the tax payers, end up footing the bill.
With a stagnant economy and high inflation, we are quite literally getting poorer each and every year. This is why our public services are in a mess and we all struggle so much. The government is now absolutely stuck. There is no growth in the economy. Inflation is high and dragging down spending power. If they choose to raise income tax next month, that will take even more money out of the economy and reduce the overall tax revenue from VAT. So essentially a zero sum game. If they don't raise taxes, then they can't afford to mantain the current level of public services.
They also can't borrow more without crashing their rating on the international markets.
We have reached a point where our economic model no longer works. There actually isn't any answer to this. An IMF bailout would be catastrophic.
The only really viable answer is a dramatic reduction in the size of the state and the provision of public services. I'm not sure what that would look like in reality. But at a minimum it would mean no council services, we would clean our own streets, each cleaning the bit directly outside thier own house. No park maintenance, local volunteers would do this. No hedge cutting or verge maintenance, local land owners would volunteers to do this.
No proactive policing, and response only for serious crime. We would have to revert to being "real" community's again and using the "village" to raise our children and keep law and order.
No NHS. Yes, this means people dying earlier, no ongoing care for chronic conditions, no provision for care for the elderly. You would have to make your own arrangements to care for your parents.
Very limited armed forces. A coastal defence, not a Royal Navy. No RAF. A Massive push for a well trained TA, but very few regulars and this would only be a limited army, no longer capable of overseas deployment. Just purely a domestic force, similar to the Irish Army and their Civil Defence force. We should try to keep Trident.
None of this is what people want. But the reality is that there simply isn't any money to continue paying for these things. Something has to change.
