I stopped after the beginning; feel free to point out any mistakes, but I think this work's understanding of power is far too naive.
Firstly, the MC, as the eldest princess, is somehow openly hated by the common people, and the hatred is directed at her personally with such specificity. If this were truly the case, it could only mean the MC is being used as a scapegoat (lit. 'set up as a lightning rod' - meaning pushed out front as the target/solution to problems). Ordinary people, far removed from the center of political power, couldn't possibly know precisely that a specific individual did specific things. The actions taken are key. Because only concrete actions cause change, which then attracts attention (whether for good or bad reasons).
Secondly, the author's understanding of feudal lords is overly simplistic. Driven by survival instinct, the common people would necessarily feel fear, awe, and obedience (at least superficially) towards high-ranking nobles who control their life and death. Open hatred would be suicidal. As for the 'kind' feudal lords—namely the MC's father, mother, sister, and brother—their wealth stems entirely from land monopoly and the exploitation of tenant farmers/serfs' surplus value. Is it really plausible that a feudal lord would see the lower classes as actual 'people'? Even 'merciful' actions would necessarily be motivated by the desire to maintain control. Isn't their 'kindness' depicted as far too romanticized?
Furthermore, the witch curses the MC, instantly transforming this privileged, sheltered eldest princess into a beggar to make her understand the suffering of the common people. In essence, this intention isn't flawed, but this is not an effective educational method; it's lazy and patronizing ('high and mighty'). The most obvious flaw in this kind of 'education' is that it's incredibly prone to leading people completely astray. The witch wants to teach the princess to be kind, but what she's actually teaching her has little to do with true kindness and is even twisted. The economic base determines the superstructure. Power is only accountable to its source. What good is 'correcting' one princess? Has the feudal system actually changed? The witch's entire operation, in my view, is fundamentally misdirecting the conflict. Is the nation's problem really just that the eldest princess personally lacks 'kindness'? No! It's the entire feudal relations of production, the rigid hierarchy, and land monopoly that create this systemic suffering! Correcting individual nobles is utterly futile! The development of productive forces is the fundamental force that breaks existing relations of production and drives social change!
