Right and wrong detract from productivity 

The only thing that’s absolute is that discussions of right and wrong often lead people to act counterproductivly. 
Anyone can safely drop the words from their vernacular and still be as productive if not more so.
Take for example, you should stop and look both ways before crossing any road. What if it’s 2 AM in rural America and a crazy guy is chasing you with a knife? Don’t you think that time would best be spent running and taking a chance? Maybe looking both ways as you run across or before you get to the road? 
You can always explain why and avoid their usage altogether. And often you’ll find that why highlights why right is actually wrong and wrong is actually right.
