No seriously, I liked what Michael Eddington said in "For the Cause"
"I know you. I was like you once, but then I opened my eyes. Open your eyes, Captain. Why is the Federation so obsessed with the Maquis? We've never harmed you. And yet we're constantly arrested and charged with terrorism. Starships chase us through the Badlands and our supporters are harassed and ridiculed. Why? Because we've left the Federation, and that's the one thing you can't accept. Nobody leaves paradise. Everyone should want to be in the Federation. Hell, you even want the Cardassians to join. You're only sending them replicators because one day they can take their "rightful place" on the Federation Council. You know In some ways you're even worse than the Borg. At least they tell you about their plans for assimilation. You're more insidious. You assimilate people and they don't even know it."
There is a lot of truth in it. And it's also true for the real world where every government believes that its own form of government etc. is the best one + wants to "convince" others to change there form of government.
