A government by the people and for the people, would be exactly the right size. It is, in theory how people organize things like maintaining roads, or taking care of the young, sick and elderly, and those who have fallen on hard times.
There are sectors of society who don't care much for that. They have their their contractors, they would not be caught using public transportation or healthcare dead -- so of course the push is to dismantle government where it can't be bought. Luckily, most of it *can* be bought, that's why there is still so much of it ^^
Government keeps getting blamed for stuff corporations bribe it to do, but is (supposed to be) invisible where it works in lockstep with them.
As for other big things, I personally hate the fact that Twitter and Facebook are so heavily used, though I don't mean those specifically, they just represent the disease. Even this forum is owned by some faceless random corporation. I'm sick of a web where not every single user has their own webspace with their own email, and where everything is run for ads and data mining. I call it "The Big Noob", it's like the big sleep, but with zombies.
I generally hate Big Media, Big Gaming, in one word, Big Distraction. What I would love is Big Journalism, with "journalism" being something that actually deserves the name. I would LOVE to live in a world where critical thought is breathing down the neck of everyone, instead of this foul odor of idiocy and greed. And, you know, BIG DEMOCRACY.
