This is what I am wondering also especially those blackhat hackers who has the ability to do a decent job if they will likely to find one.
There are few reasons why they keep on hacking or scamming rather than working. Either they are wanted or they have a bad record in their government so they cannot find a decent job. But I saw that scamming or hacking will take time, therefore most of them really focus on what they are doing so I cannot label them as lazy instead they have a reason behind their actions.
Black hat hackers usually prefer to hack instead of doing the same activities as ordinary employees. It is debatable to go to work or do the job which you want to continue for a lifetime. Both choices depend on the person.
