But it is subtle manipulation. How many articles have you read about failing schools or school funding challenges, and how often have they mentioned that the U.S. spends among the most in the world per student for K-12 education? As you say, presenting news without context or analysis isn't journalism. But the minute you start picking facts for context, or analyzing the facts, you're inherently incorporating your personal views.
That's not "subtle manipulation", that's bias. Calling it "subtle manipulation" disingenuously implies that journalists unscrupulously distort or change the news. Context & analysis is inherently biased, no surprises there, but you're approaching substance-free cynicism when you say stuff like "Journalists don't believe it's their job to talk about why something may or may not work, but they really want to."
