Here’s a pitch: The three great democratic arts are law, education, and journalism. You need skilled practitioners in each, free to do their work openly in the public sphere, in order to have a healthy democracy. Specifically a meritocratic democracy with true social mobility.
I’ve seen the phrase “democratic arts” plenty of times, but never attached to a list like this — though it’s possible I’m unconsciously cribbing it from somewhere. I like these three because, besides being concrete and important, they’re each fun.
