Laziness is in reality fear of failure and not having the required skill manifested in the human quest to be useful and productive.
Now the being productive part is the real human nature .Add to it the power of imagination and then the knowledge that society teaches you from your childhood of being better than others as a prerequisite.
Being natural and what you are is the way everything else in nature behaves but human beings because of their free will consciousness want to be better than just be.
The benefit of this free will is that some people convince themselves to do somethings that are at the minimum acceptable as good work by the society.
Once teh complete knowledge that every human being is innately prodcutive and useful by just existing is there in the society and culture you will find no one Lazy .
