Bowie wrote the song for Mott the Hoople. its originally a part of the Ziggy Stardust story:

""The time is five years to go before the end of the earth. It has been announced that the world will end because of lack of natural resources. Ziggy is in a position where all the kids have access to things that they thought they wanted. The older people have lost all touch with reality and the kids are left on their own to plunder anything. Ziggy was in a rock-and-roll band and the kids no longer want rock-and-roll. There's no electricity to play it. Ziggy's adviser tells him to collect news and sing it, 'cause there is no news. So Ziggy does this and there is terrible news. 'All the young dudes' is a song about this news. It's no hymn to the youth as people thought. It is completely the opposite. "
