I would only ask how much difference there is between the NSA/government and parents when it comes to actually caring. I somehow doubt that the former really cares about people, whereas the latter do care about their children.
I'd say none. These things always start with a desire to care for/protect X. But than as circumstances extenuate more stringent measures are needed. So before anybody realizes what's happening an NSA class invasion is born.
Baby steps and good intentions...that, is precisely how anything goes to shit.
You're giving the government too much credit and parents as a whole too little IMO. I don't think that most gov't applications start out as anything other than a power grab.
