I agree. And often, people don't draw the line at corporations. So many people in America are willing to screw over others if it means another dollar in their pocket.
The base elements of human nature do not care about national borders. I think you'll find such people, in similar proportion, in most places around the world.
"Fucking over others for personal gain" is actually not a "base element of human nature"! Plenty of other cultures are more altruistic, more about raising everyone up.
