What has David Hogg done to deserve being DNC vice chair?

Genuine question what has David Hogg done to warrant being dnc vice chair? He is genz and not quite 25 years old and from information he’s never done anything at all besides a “boycott of the ingraham angle” and fighting for gun control.

So genuine question what has he done if anything to actually warrant being in a position of power? Is it just feelings and the way he speaks? I’d rather see a hard working person who started their own business and came up from small beginnings who actually has some actual experience and understandings of how finances work.

Instead we are getting another spoiled brat who has ideals but has never actually fought the fight for the ideals. That’s just my opinion?
