Actually I think that the idea that “idealism can replace expertise” pervades a lot of the left and even well intentioned liberal volunteerism

From “I have no knowledge of agriculture, have never studied it, don’t know about terrain or soil quality but because I want everyone to have plenty of food my plan will totally work and not cause a famine” to “I’m a random college kid with no construction experience but because I want to help people my building houses or schools or whatever will turn out great”. Idk, I think we often think being good is a substitute for being good at what you do. You have to be both. It’s so strangely arrogant to think idealism means you don’t need knowledge or training
