My opinion of them is somewhat higher. Perhaps the minority of them of which you object are a little more visible than the ones who are out of sight working and studying. Clarence Louie would be a credit to any demographic.
I sometimes think it's due to the environment in which they are raised.
A woman in my wife's family had a son from a native from Moosenee....The man was the laziest bum I had ever seen....had a do nothing job for a provincial institution here in town, and getting up to go to work where he had practically nothing to do was too hard for him. He finally quit and went back to Moosenee, to do what ? I don't know and don't care enough to find out.
The woman raised him with the man she finally married in a quite different setting, where his uncles all worked at steady jobs....
They got him his status card because it was easier for him to get accepted to college...and when he finished school, he promptly got a job, and hasn't stopped working since at several different job locations.
You see the same thing with several generations of welfare recipients, until one sometimes breaks the mold and gets out of it...
