I'm not crazy, the attack has begun.
I think you need to dwell on this a bit.It's important to understand that when most economists say taxation is 'fair', they don't mean proportional (and especially not regressive), but progressive i.e. the rich pay a higher percentage of their income than the poor, even for the same amount.
Who is getting the cream of cash-saving benefits from BEVs?
Who is getting creamed on fuel duty for only being able to afford bangers, nor able to afford houses with driveways?
Just the other day, 'one of our colleagues' here was happy to announce how he'd go fill his boots at tax payers' expense at the weekends rather than charge his car at home.
If you want 'the poor' to be able to afford new BEVs, then maybe some money needs to be put back in their pockets.
Here's a storming idea; tax credits for fuel purchases .. all your duty refunded if you put it towards the purchase of a new BEV.
Top idea, I think? What say you?
