They do... what you see there in the "4,000 page" bill is legislative language - pretty clear code for a lawyer or legislative aide. On the other hand, the Congressional Research Service puts out some pretty good nonpartisan "plain-language" bill summaries (and for anyone who asks "well why don't they just use those the laws themselves", ask yourself "why don't you just write code in English" - they both have the potential for ambiguity).

Incidentally, I put "4,000 page" in quotes because it's a pet peeve... if you actually look at the text, it's in 24pt font and giant margins - makes it much easier to read and mark up around a table, but in no way approximates the amount of text people envision when you say "X-thousand pages".

Yea but if you compile it, wouldn't it be faster than being interpreted? And the interpretor is also a human brain, which is much more error prone than a computer.
