Indeed, it's not a sufficient condition. The population has to be educated and civilized so they respect each other's rights.
Moreover, just having access to management doesn't mean those on the lower rungs will use it. We may technically have the freedom to lobby our political representatives, but how many people care to do so? Those nonprofessional lobbyists who do so will be the loudmouths, the worst who are full of passionate intensity (via the Dunning-Kruger effect), to paraphrase Yeats.
So we'd need to be educated also to respect our responsibilities as citizens. Instead, I fear we're brought up more on the torrent of corporate advertising we watch, which turns us into consumers rather than responsible, autonomous citizens.
