That's like saying "I'm not going to pay my taxes (or a higher license fee) until the government (or CART) only spends them on things I approve of".
I'm sure many people -- me included! -- would love to be able to do that, but it ain't gonna happen... 😞
We elect a government and they decide how to spend the money, because that's their job -- and CART work the same way, but they're obviously not elected... 😉
In real life if we want better services - NHS, rail, social care, roads, police, courts, canals -- they either have to be paid for/subsidised out of general taxation from everyone, which is not hypothecated -- NI was when it was introduced but has not been for many years -- or by fees paid by the users. In many cases a subsidy from central government to make something good for society affordable (e.g. rail transport, especially into cities) is needed, because left to the market these would die and be replaced by cars (see the USA) and we'd have gridlock -- good high-density public transport is too expensive if it's only paid for by users, and the canals are too costly if only paid for by boaters.
The real problem is that because many politicians have been lying to people for years, lots of people think they can have better services without either higher taxes or fees, that either somebody else will pay or it'll come from magic money trees like "improved efficiency" -- and it simply isn't true. And no amount of Tory/Reform party manifestos will make it true... 😞
This applies equally to services like the NHS (paid for by taxes or charges) and the canals (paid for by DEFRA or boaters). The money has to come from *somewhere* and in the end that means *us*, one way or another...
