The UK macro policy problem is like the classic Irish joke about the lost traveler who asks a local farmer how to get to Dublin.
Farmer thinks for a bit and replies, "Well, I wouldn't start from here."

So this is sort of fascinating because on the one hand obviously the Roman imperial senate was a shadow of what, say, the Senate of the third and second centuries BC had been, but at the same time it was a pretty crucial component of imperial governance into the third century.
You ever think about how the Roman Senate kept meeting centuries into the reigns of emperors. Hanging out, shooting the shit, giving speeches, and play-acting that their positions of privilege remained positions of power.

You can see some of these stereotypes - the simple, morally pure countryside vs. the morally compromised, inauthentic city - play out in Greek and Roman literature.
So this is a very old idea that recurs regularly.

Do other countries have this weird notion that you’re not a “real” representative of the nation if you live in an urban center? Like do the French say Parisians aren’t really French? Are you considered not a real German if you live in Berlin? Or is this mainly a weird American thing?

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

The fundamental problem:
58% of voters want public spending maintained or increased.
67% want taxes to stay at their current level or be cut.
In reality, it’s a binary choice. Taxes go up, or spending is cut. That’s it.

"The government needs to take ownership of the Budget and use it to construct a convincing narrative. That means not blaming the OBR or HMT but explaining why tax reform is necessary, why it will be good for growth and public services and how pain will be fairly shared.

Blaming the OBR for the Budget maths is a waste of time
The government must explain why tax reform is necessary and desirable for fiscal sustainability
