How Far Away Are We From Wartime Paucity?

I worry about the worried well,
who say they are not hypochondriacs
whilst they are held in thrall
to the latest glossy adverts
for the latest glossy boosters to their health,
whilst in 'the developing world'
what that world develops is wars
and shortages where nobody dares to ask
'How far are we from wartime paucity?'
