It still exists. That's one of the reasons it is the "Golden Rule".
I follow the golden rule. Recently, I find that if I stick to the golden rule and then somebody else comes along and tries to hinder my survival, not because I've done something to deserve it but because they are selfishly forwarding their personal gain, they get instant karma.
For example: Girl at work starts stealing and attempts to set me up as her scapegoat. BAM! Instant karma, she gets discovered and fired.
The moral of the story, follow the golden rule. Act in the best interest of everybody involved, not just yourself, don't hurt other people. And you'll be alright.
