I think you are missing the key point of this election.
That the tories have said they would do all sorts of things (e.g. get the economy growing, stop the boats, get waiting lists falling etc etc) and failed to do any of them - indeed in many cases the stats show the situation to be the worst it has ever been.
So the argument is about competence - sure both labour and the tories claim they will reduce waiting lists, but they key is whether labour will actually succeed - the tories claims ring hollow as they've been in charge, and failed to do it so why would you expect them to be successful when their track record is one of failure.
And the most critical one here is economic growth - this has been woeful since 2010 compared to 1997-2010 (including the financial crash). And the most painless way o generate more tax revenue and more cash for public services is by growing the economy. Even Truss understood this (although the notion that you borrowed money to give tax cuts was nuts on stilts). If labour can get the economy growing and provide the stability that businesses need to make long term investment decisions (as they did post 1997) then that will unlock massive change compared to the past 14 years.
I entirely get the point of the election and none of your post addresses that the policies in terms of turning ship.of state around are pretty identical from both Tories and Labour.
Yes, there is the question of competence, and I have a known incompetence, against a guess. Even that known incompetence is questionable since Sunak is trying when not making laughable faux pa's to push the idea that through Covid, he was responsible for keeping the country afloat, and whether you agree or not, Labour didn't argue for substantial alternatives, and that he's repaired the Truss folly., just as Starmer might tout repairing the Corbyn one.
A lot of what happens to the economy, the govt is essentially a bystander for. The claim that the inflation rate has come down due to govt action when they aren't saying it went up because of them illustrates the problem.
I'd very tempted to vote, if I knew.who they were, for Napoleon's idea of lucky generals. The Tory Party is currently desperately making 500 quid on inside trading because they have lost their beliefs in their ability to spell lucky never mind actually be lucky.
The Tories need time in retreat to stab one and other, and work out what they are for again. That doesn't mean that Labour are guaranteed to do anything useful other not be Tories. I fear that dependent on the make up of the Tory MPs after the election they might embrace Farage as the Messiah rather than the very naughty boy
