"Welp, time to get to work making the world not retarded... though my version of not retarded is probably pretty retarded to some people... eh, if they don't like it, they can kill me and take my place (worst sentiments ever). Anyway, onto to many reforms!"
Yeah, a lot of people would have to be killed... let's see... all politicians from before I was ruler of the world. Sorry politicians who actually want to do good things, but I can't be sure that you actually were trying to be helpful, so you all have to die. Next, I will protect most forms of media; I might fight one or two types of media objectionable for certain age groups, but pretty much, if it can be made without a real person being killed/hurt, than go for it. Religion is... tolerated, but no aggressive proselytizing, capiche? Otherwise, sure, go ahead. But you can be sure that religion would be watched VERY closely. Other than that, basic stuff (general equality before the law, programs to make that equality more of a social norm as well, because than the laws are less needed, etc, etc).
Also, everyone will start learning a second language as soon as they start speaking (and showing a modicum of proficiency at) their frst language (on average, this should be about the age of 3-4). That doesn't mean you have to speak two languages, only that you have to try and learn (I do it like this because for some people, like myself, learning two languages may very well be an impossibility. I couldn't even learn one language, and was mute, until I was 4 years old and I went to a special school for speech. Even then, it took a damn long time for me to actually learn English). There are no requisite languages; it can be French and Italian, Mandarin and Russian, whtaver and Whatever.
Note that, since many modern Chinese languages use the same written system, even though they are unintelligable to each other when spoken, if you are a Chinese [erspm who speaks, say, Mandarin, and you chose to learn Cantonese, you would have to chose one other language as well (yes, even another Chinese language based off of the same written characters), if only because when I say one has to learn another language, I mean completely; written system and that which is spoken. If this seems unfair, well, chose a language with different written characters.
Anyway, I could, like many people, go on all day. The language thing only popped up because of the China courses I'm taking this semester.
