that does exist. you're not getting it though.
in USA you can get a decent lunch for a decent price.. but only when it comes to jeans and food.
when it comes to 21st century things like mobile data plans and warranties on consumer goods americans are getting shafted.
like fuck, why can't you just have a 24 month warranty on it? do you really want to buy shit that the manufacturer thinks will break in 3 months? seriously? shit that you buy on a fucking plan that you pay for 2 years mind you!
in other parts of the world unlimited means unlimited as well. no 2 gig limit. no 5 gig limit. no 30 gig limit. I got a 300kbyte/s torrent downloading over a mobile connection as I write this - of course, not in the USA, in the "sticks" in a country with a far less population density than USA - this area population density wise is comparable to rural arkansas and much much less population density than rural north east of the USA. oh and the monthly cost on that connection is about twenty bucks, ten bucks would get you a "slower" 3.5g connection. still unlimited though.
the thing with mobile data transfer limits is that as long as you have those then people will very rarely even hit those limits - people adjust their viewing habits so that they don't view youtube on them, so that they don't do fucking anything with them because they'll feel bad when they look at a mobile website and see that their precious quota is being drained by autoplay video adverts! .. and as a result the phone company wins again - they don't have to build a decent network because nobody is using it like it's the 21st century.
