Is everyone so cruel these days?

Why are people so harsh today? Whether you're driving a car or just walking down the street, someone will constantly shout at you or say horrible things to you for no apparent reason. When you're at the mall and someone bumps into you without saying sorry, they don't want to socialize with me, and when I attempt to be nice and ask questions, they are unfriendly. Why is everyone so mean nowadays? Is this the norm now? When I go into businesses, no one welcomes me; there is no customer service. Bus drivers are constantly unpleasant and snooty, shouting at me all the time, as if everyone is such a dick for no reason.
