How did The United States of America become so anti-social?

I've talked with people in Canada, The United Kingdom and even Japan they seem open to communicating however here in The United States of America everyone basically growls at you from their smart phone if you attempt to converse with them it's down right mournful.
Update: I'm from The United States of America I meant people from Canada, The United Kingdom or Japan are more sociable than those born in America.
Update 2: Why are you question whether or not I've spoken to people from other countries .
Update 3: "It's actually doing our country a service in keeping crime rates low." You must be joking...
