With your reference to VED and Fuel Tax are you saying a poor person can be expected to have a Car ?
Just what is your definition of a "poor person" ?
I'm not defining a "poor person" as someone who is destitute, simply someone who has enough to survive but nothing more. I know some think only the destitute are in poverty, but I think poverty, like any measure, is relative.
Of course a poor person can be expected to have a car. In fact, they're more likely to be forced to have a car, regardless of cost, as they're more likely to be working antisocial hours when public transport doesn't operate.
The changes to VED don't affect current cars, at least, but VED is charged according to pollution and not according to the retail value of the car. Given that hybrid cars, or cars with "green technology" like turbos, tend to be significantly more expensive than standard cars, I'd say this is regressive. It's the same with fuel tax; the poorest people will be driving the oldest cars, and by their very nature are likely to be a lot less economical.
As for Corbyn, I think it'll be interesting. In the current electoral system I don't see him winning a general election- elections are decided in a handful of shire constituencies, who aren't going to vote for a leftie- but I think he'll make a better job of things than Brown or Miliband ever managed to. And I think he'll make a better job than any of the other candidates: Burnham's tainted by his time as health secretary, Cooper by her husband (much as she shouldn't be, she is) and Kendall is just another vacuous Blairite who'd serve up yet more Diet Tory policies.
At least someone like Corbyn might have a chance at getting the Scots back into Labour and, free of the threat of the SNP, I'd expect to see some of those who voted Tory, Green or UKIP go back to Labour. He'd even tempt me to vote Labour, and I've never voted for them in my life.
