Yakuza

[Clouded Sky]

Additionally, they provided a means for the Burakumin, the outcasts of Japan, to enjoy a decent lifestyle. Though discrimination was officially done away with after the Meiji restoration, a lot of that prejudice still remained - many yakuza could have cared less about the type of person as long as they got a productive member for the group.

And they unite all people with their nation...

I realize this sounds silly, and while it wasn't to a great extent, it was an "upside" of the yakuza. (Oh, and it's true.) Otherwise this is mostly romanticized.
