Isn't the current system in the UK, US, etc., indeed too classist, though? What specifically was too much for your liking about Disraeli's views on that? (I'm not familiar with them, myself.)
Ignoring Disraeli for a moment, I'm a strong proponent of social mobility as an important concept in a healthy society.
So, whether that society is arranged in a class-basis or not (and I strongly prefer not) concepts like access to high quality education right through, healthcare to all, etc are important concepts to me.
One of the reasons I see them as important is that I want to give people an opportunity to advance on their merits, and achieve 'better' for themselves and their kids based on their efforts and ability.
My understanding of Disraeli and ONC more generally is that they would similarly see education and health (as examples) as important for all. So in a broad sense, they might align policies with what I'd like, at least in a basic sense.
But that is less to do with concepts like social mobility, and more to do with a belief that the 'elites' in society owe it to the rest of society to use their power to provide for them.
So...at some level, I'm fine with that. Those with more should help those with less. But I suspect at some level of detail, I'd be directly opposed to ONC because it seeks to improve workers lots in the class they're in, whereas my preference is to idealise a meritocracy.
That makes it sound more clear cut than it is, I suspect. And Disraeli did end up with a title (an Earldom I think?), after having been born in a less affluent home situation, hence my comment about him embodying social mobility to a degree.
I'd be the one refusing to take the title, end of the day.
