Crap I hate when nuance gets in the way. So yes laziness can exist on an individual basis. Though would you call this lazy or did his parents fail him. Providing an environment where he was rewarded/coddled without having to put effort in. Also I find that sometimes people like this have undiagnosed mental health issues and are self medicating.
What we are talking about here is laziness as a concept when applied to a group of people. The poor for example. Where is it not their willingness to work that keeping them down, but giving them the label of lazy is justifying not providing them with the opportunity/help that would let them succeed.
If you want to learn more about it. Why it exists, and how it is used to justify the rich and the poor. I would recommend the freakenomics episode. Once you understand it better. You start to see how loaded some of the language and idea society takes as fact are. And by the end you will wonder why are you working so hard.
