If she upped personal tax allowances to £13000 then that'd give people more money to spend.
People like spending money and surprisingly enough it's what keeps the 'economy' going. It all being a coffee shop economy currently.
To get people spending big chunks of money on cars and houses would require strong and stable economic forecasts. To achieve this she needs to u-turn her employers NI rise and do something positive to help employers help people.
Maybe something that would also encourage them to take on people with ill health and who could be supported easily into work.
Looking at wider things - encouraging industry is unlikely to happen (why any company wants to invest in this country with high energy prices?) unless an encouraging tax regime is created.
And a takeaway tax and enforcement on every one who delivers food to ensure they are properly paying tax would be beneficial.
A review of the state of the highstreet and potential money laundering shops needs to be looked at - no point taking tax from fake businesses if it actually serious damages the economy in other ways.
We need cheaper energy and cheaper housing. Neither are likely under this government. But the number of migrants coming to do jobs is insane and needs to stop.
Students are a huge lifeblood for the university system but that in itself has damaged it beyond belief and taken many towns into the "uni land" clown world which means it's actually really not positive for the country.
We can not import the rest of the world here and I think our own trained people should be priorisitised for work in the NHS (nurses, doctors, midwives etc)
1/3 pensions, 1/3 malpractice payouts 1/3 on real NHS is not sustainable.
I'd streamline the civil service too and ditch huge numbers of the newly recruited lot and I would stamp out the appalling work ethic of "I can do what i want when I have finished my work" nonsense that exists.
Significantly I'd look at the number of children's homes that are making money for private companies, buying up properties and costing about £1M per child. That's one of the reasons why councils have no money.
We need to get better at spending money wisely across the board.
