A person who does nothing with their life when they could be doing something is really a narcissist. They take it for granted that others will support them even though they contribute nothing and they don't understand that there could be any reason to work hard other than their own immediate pleasure. Ironically, these people often complain that the reason for their situation is because others aren't doing enough to help them. In their minds, it's not really their fault that they are failures and they go to great lengths to convince other people of these lies.
