Ethical fading a term coined by Simon Sinek in his book Infinite Game refers to the situation wherein people compromise ethics for short term gains..
Also supported by the following quote of Daniel Pink , shows how ethical fading can be accentuated by short term finite minded thinking..
“A lot of times when you have very short-term goals with a high payoff, nasty things can happen. In particular, a lot of people will take the low road there. They’ll become myopic. They’ll crowd out the longer-term interests of the organization or even of themselves.”
