It's worth considering the extortionate university fees in the US as well. A hundred grand (GBP!) just for tuition at top colleges. A US high school diploma won't get them into university in the UK (unless school offers an IB programme).
Au contraire, many students from my local public high school are successful applicants to UK universities every year, without the IB. Students who have done AP courses and who have done well in the AP exams are very welcome in top UK universities. DD4 is also friends with a student who is heading to Germany for university.
The cost of instate tuition plus room and board in many states can be far less than those costs in a private university. In some states you are basically getting an Ivy league education for well under the Ivy League cost - lucky residents of Michigan, Pennsylvania, Virginia, Illinois, Wisconsin, North Carolina, Massachusetts, Vermont, Texas, California, Ohio, Washington get first dibs on a first class education. Admission is highly competitive.
...not sure I have ever been believed but I have never seen a gun in my time here (25 years) outside of a police or security person's holster. In 25 years I have never been the victim of any kind of crime big or small. My children worry about the issue of gun control in the US but they don't worry about violence to them from guns. They are also exposed to far less tolerence of alcohol and drunkenness - yeah teens try drinking but there isn't the same "ah well all teens drink, right?" attitude that I see on UK MN and in Ireland.
Agree with Pallisers.
I regularly leave my back door unlocked, even at night. You can leave your children's little toys out in your (unfenced, unhedged) front garden overnight and they won't be stolen. People have block parties every year on summer weekends. For the most part, people obey leash laws and pick up after their dogs. People go out en famille for trick or treating. People swop hand me down children's clothing and equipment and winter jackets/snow bibs/boots. People go to wakes. People sit out on front steps chatting on summer evenings. You get to know your neighbours. There is a fantastic and well funded local library system offering all sorts of programmes for all ages and interests, and great parks, playgrounds, pools and rinks.
I have been mugged once since 1988. The only experience of violence I had was actually from exH and the police arrived within minutes of my call. I live in a nice suburb where there is zero tolerance for graffiti and excellent communication between the police and the schools. Yes, students dabble in drinking and drug use, but as Pallisers says, the public level of tolerance for that is not there and the school has a fleet of social workers and other student support services to work with families if there are issues.
Fifteen minutes on foot from me are the city limits of a huge city and on the other side of the street that separates us is one of the most crime ridden areas in that city (gun crime, knife crime, drug sales, prostitution, petty crime, rape). Thousands of people board the local trains daily and travel through the blighted area to work and then home again, and just for leisure in the city too. I still haven't seen a gun or even a knife apart from the guns of the police. The school does lockdown preparedness, which nobody likes, and so do the local private high schools.
I am quite torn really, about the fact that it is possible to live in such a bubble. On the one hand, 'vive le bubble', and on the other hand it troubles me and says a lot about the US that where you live - which translates to how much you can afford to pay for where you live - determines so much of your quality of life for better or for worse.
So much of the culture of the US depends on where exactly you are. I live in a very blue area of a very blue state. People are willing (more or less to pay top dollar for excellent public services - the public school facilities are gobsmacking, easily the equivalent of the very best private schools in the UK, and students go to Ivy league and other top universities from here every year, and also to the Olympics - and local government in my municipality is very self consciously transparent. Attitudes are very different elsewhere, I realise, in terms of social conservatism/approach to taxation, etc, and on top of that I can name several suburbs near me and also the local big city where corruption/mob influence is a dead hand affecting every aspect of life when you boil it all down.
