We use language to create distance

We use language to distance ourselves from the impact of our decisions. We use and overuse euphemisms such as "companies would never spy on their customers", but we love data mining.

The danger increases with the slippery slope. When somebody use unethical behaviour and gets away with it or even rewarded for it, then does it again and bigger than before. Then other people join in and before you realise, you have full unethical fading.
