That's a nice sentiment in a vacuum, but we're not in a vacuum. It's sort of like focusing on getting every child a college education when you can't even manage to teach them all literacy yet.
At the point, I feel like the priority needs to be around figuring out a way to defeat disinformation and misinformation to restore some kind of common ground understanding of the facts. The marketplace of ideas can't function if major factions reject truth-seeking in favor of blatant lies that are appealing for various other reasons (e.g. emotional satisfaction, ability to manipulate others, etc.).
