People would need to see a real increase in their income relative to prices, in the order of at least 10-15% more, plus all the usual: better NHS, able to find a dentist, care available for grandparents, social housing available for young adults, etc. etc.
You either have to raise incomes, or reduce costs, PLUS raise taxes to fund the services and NHS.
It is generally not possible to lower prices, e.g. at supermarkets. So you have to raise take-home pay whilst still raising tax.
We are taxing the wrong things in this country.
So, raise minimum wage again, offset by big reduction in employers NI so jobs are not lost.
Sort out the stupid cliff-edge of taxation/childcare at £100k. Give everyone back the personal allowance.
Raise the 40% rate threshold on income tax from £50k to £60k, and add a new 50% rate at about £150k and a 55% rate at £500k (in addition to the 45% rate at £125k).
Reduce the cap on what you can pay tax-free into pensions from £60k to about £40k or less.
Raise capital gains tax, dividend tax, and inheritance tax.
Consider a sales tax on online sales if the company does not pay UK corporation tax and UK VAT.
Maybe introduce a tax on currency conversions.
Maybe introduce a land-value tax to replace council tax, paid nationally to central government, so that there is less difference between counties.
Consider rent caps in overheated rental housing markets.
Get serious about building social housing - the actual government employing people to build, not just leaving it up to the market.
So many more ideas.
It just takes a huge majority and a leader with guts.
Starmer has the majority, but not the guts or vision.
