What Arabic people? Iranians are not Arabic. Most Palestinians are... but I don't think we're supposed to mention that as we're meant to pretend they're the helpless indigenous population and the Israelis are the evil colonisers. When obviously it's the opposite. We, America and even Israel are allied with the actual Arabian nations, and are currently trying to defend them from attacks by Iran and Iranian proxies. Which I'm sure you'll be happy to learn.
As far as Burnham, he's so far announced some piddling, un-costed policies which will have little impact. Other than for the very wealthy or wasteful, who might appreciate the lack of VAT when running a mansion. For most of us it's entirely meaningless, and as apparently we don't have much money, one thinks it could be used for something more useful. As for buses, providing some more would be a far more sensible use of money. Most users don't pay anyway, and as has already been seen elsewhere when caps are introduced, bus companies will just change routes to make sure they don't miss out on profits. So a £3 single on one bus will very possibly turn into a longer journey split into two for £4.
But even if that doesn't happen, and the (non-existent) buses are cheaper for the minority of people who actually pay to use them, it seems like the most absurd way to start. How can he possibly think the country's most pressing needs are reducing £3 bus fares and saving an average household £4 a month on electricity? It's naked populism, done badly. Social care is indeed a pressing issue, and one would think he'd want to put every penny he could towards that. Especially when we are almost certainly not going to like what he's proposing, any more than we liked it a decade ago when he first suggested it. If I were one of the other parties, I would keep well clear. There's no chance at all this nasty little man will give them any credit if it goes well, so why would they bother; he's spent a career taking credit for everyone else's work, it's jolly unlikely he'll change now! Of course when it fails, he'll blame them for not supporting him. But as he'll also obviously blame for its failure if they do join him, it makes little difference.
So no, I don't think it's at all a good start. Obviously I may be wrong, and I genuinely hope I am as I have no idea what plan C is.
