He didn't before when he was Chancellor, but as PM he might start believing that. Electoral Keynsianism will be very tempting, same as it was for Bozo.
He thinks he's found a tax cut here, predictably. I support fees because I think higher education is a special case in terms of public services being non-universal, non-needs based and very expensive and (mostly) financial benefits to the person. But that doeesn't mean that the government ought to put nothing in to it, which is what Sunak wants. For what the government puts in, it gets massively more back through foreign fee income, soft power, research, never mind having a more educated public. If there are some degrees that don't make people rich, that doesn't mean they're bad. My modern languages course at Oxford was terrible but got by on the university brand.
