The fact that they're not upper-upper doesn't change the fact that a public school education is a fast track to Oxbridge and to insider status.
But even with the fast track, the upper middle classes are motivated by anxiety and envy about not being upper upper enough. The original article almost highlights this, but doesn't quite hammer it home.
The class system is about aspiring to become the kind of person who has ancestral money and some huge houses. (Not just one huge house. That's the entry level.)
But the people with the ancestral money and huge houses are neither special nor interesting. They're groomed for confident self-interest and social polish, but they don't actually do much except cream money off the markets, order inferiors around, and breed.
Their self interest sets the tone for those lower down the tree who aspire to be like them. That's why they're so toxic. They're hostile to any kind of collectivity which erodes their "natural" privilege.
And they'd rather own a country which is falling apart than lose some status in a country with more social mobility which might challenge their self-perceived high status.
*Note for non-Brits: "public school" is the British way of saying "private school"[1]

The Wikipedia link I provided has the details.
When push comes to shove I wonder whether people who are anti public-schools would welcome this style of government - in a country where people are free to do what they want, people will spend a huge amount of money for their children to get advantage/opportunity.
How do you negate this? Should you negate this?
The public school track really isn't the advantage some (including the schools themselves) make it out to be; it's a well-known trope among the middle classes that a merely diligent straight-As student will have a much better chance applying from a state school than from a public school.

You see the same effect with grammar schools (in the U.K.) or magnet high schools (in the Us) which feels a little more egalitarian, though of course the availability of such schools can vary a lot geographically (and a higher cost of living near good schools can push out poorer parents too.)
I don’t really know what the solution is. It seems unmeritocratic to expect universities to take only 7% independent school students (for one thing I would expect they make up slightly more than 7% of the university student body; for another this would probably have the undesired effect of having the 7% at Oxford and Cambridge mostly made up of the top public schools) but it also feels slightly unfair to only look at grades (indeed the universities do try to be more accessible and take into account the fact that some students have depressed grades due to poorer schools)
