They do it when your a few days old because that's when you have the most Vit K in your body, if you get it done as an adult, make sure to load up on the stuff before you go it to get it done. Also, it's more or less a religious thing to have children circumsized. Most people in America don't realize that it's a biblical thing and it just kinda got meshed into society... and I'm sure the extra money on the bill probably motivated it to go further.
Also, I think that it's the parents place to decide whether this happen to their kid. If they don't, great for them, but if they don't, it's not a big deal. The mother had to go through nine months of hard labor for that kid and both of them had to work their butts off to pay for all the crap that babies need. I don't think anyone should be mad at their parents for having them circumsized. If you don't like it, get restoration or deal with it.
IMO
