Insurance is expensive over in the States.
Here in NZ I pay the roughly half what you guys seem to. (US$ 710'ish' a year). In NZ WRX's are a high risk car too, quite high premiums due to them being #2 or 3 on the most stolen list. I'm 37 and haven't had any claims with my company, have house with them as well.
I guess it's a little different, as here we pay a registration tax every year of around US$ 180, which goes towards our 'free' healthcare, among other things. Also a portion of the (excessive) tax on our fuel goes to that as well.
Probably ends up being similar once you add it all up, it's just payed through different routes.
