Not really. The next government can just decide to do something else. Much as this government has changed it's mind on several matters of fiscal policy over the last few weeks.
Things are timed in a way that may allow them to say how wonderful they are - we've been hugged again etc. Much of the budget is aimed at keeping the public's spend up as much as possible and prevent hitting the low income end too hard. Seems on average people are going to be £1700 PA poorer - some pundit but no idea of what happens with power next year. Pain is said to come after the next election. I suppose that is the increased taxation - allowances remaining the same. Inflation will drop off
I hope but that doesn't mean prices will fall but if countries want to sell stuff here they may a bit. Then comes mortgage cost increases.
Labour have some ideas about raising more tax that wont hit the general public. Mentioned 2. Ending the charity status of private schools and some sort of change to non dom status. I'd guess they would play around with other areas as well such as the capital gains type areas etc.
Well it is at least more money and really it makes sense for all tax payers to pay more really. Currently the intention is for the "workers" to pay the debt off over a rather long period.
Some pundit comments. You can not run a state like the UK has at USA taxation rates. Some countries are more successful and pay higher taxation.
I'll add one of my own. Who is going to vote for a party that said look we do need to raise taxation.
One thing that strikes me is that people were probably better off under the set up when Wilson was PM. The money we pay out has to include that which goes into various privatised entities and in council tax now. True or false, pass but I sometimes wonder.
