I agree with that. In fact, my main point was about schools being good for mages, since the Circles and other systems already provide education for them. Also, that those education systems for mages are insufficient by themselves to deal with the most pressing matters about magic in Thedas. Each society has to complement them with other things.
I agree that the schools in the Circle are good for the mages, but the dystopian part of me occasionally wonders if they're too good. One of those not-really-reforms that could be tossed in the mix of the Circle Reformation Stew would be to give mages concessions in one field in exchange for changes to their education in others.
I doubt many people would find it particularly objectionable if, say, the mages were forbidden from having and studying treatise or war, insurgency, how to run rebellion, or openly seditious literature. Now, toggle that to the extremes a bit...
People blast the Chantry for indoctrinating the mages into self-fearing and subservience through propoganda, but the Circles have nothing to the academic rigor of, say, a North Korean curriculum.
About education for all, that would be a good objective by itself, magic or not. Hell, it's an objective we're struggling with in our real world, so I think that Thedas can take its time. I agree with previous posts that a better educated population may have a more positive outlook about magic; however, it's also insufficient even if Thedosian societies managed to somehow provide free liberal education to all. Because it can make you think that benefits may overcome drawbacks, but can't make you ignore the drawbacks. They will still have to be dealt with.
Or, alternatively, education could be presented in a way in which the unacceptable costs and risks outweigh the gains, and so education vindicates mage suppression rather than opposses it. As inspirational as 'the truth shall make you free' can be in abstract, in practicality there are plenty of contexts where an informed decisionmaker would disagree: sometimes the truth is bad enough to warrant extreme measures.
The Chantry is the main provider of education, but only to people who join their ranks, be it as brothers or sisters, or Templars. Religious education, mainly, but Genitivi and others prove that a scholarship career may be taken. Nobles can afford private tutors. According to Merrill, among the Dalish Keepers and Firsts learn lore and history while the rest learn hunting. Nothing strange here. More strange is that Circle Mages receive a very good education, Shaperate archives have less limited access than normal for a medieval library, and Qunari use education as a tool of assimilation and conquest.
The Chantry also teaches the public, albeit along religious lines. It isn't formalized, but it is what most people get.
Amusingly, I consider the Chantry the most plausible origin for any Thedasian equivalent to liberalism. It is the only major belief system that both is open towards individuality and has a core belief set that justifies, rather than refutes, the idea that all people are equal regardless of race.
But education can be serious business. The Masked Empire began in the University of Orlais, after all. The key matter during Celene's conversation with Morrac was that there wasn't anyone in the university capable of explaining Vyranion's Theorem. That is, that a Tevinter scholar could shame the biggest learning centre in the Empire. Their refusal to accept a promising mathematician just because he was an elf was hindering Celene's efforts to beat Tevinter in that particular area of "soft power".
Speaking as myself, I think soft power is quite overstated in many contexts. I think Celene's focus there ignored the very real hard power concerns that should have concerned her more.
