PRODUCTIVITY

Oil, illegal drugs and Big Pharma.

These are three of the four biggest businesses in the world.

But the fourth is also the largest and most profitable.

It is also the one least discussed in public.

Armaments.

You know, guns, bullets, bombs, planes, drones, Humvees...

These little enterprises, which prop up the economies of most producing countries in the world, are almost a secret.

How refreshing - if gruesome - then to see a major report in today's morning Sun:

Canada doing brisk business in arms: data

Military hardware exports rise

Of course, you can't sell a few killing machines without helping out the odd despot or mass murderer or two.

Just turn the page and read about the half-million people huddled together in refugee camps in Kenya. Dadaab is hell on earth. And after the famine and the drought, came the war.

But hey, our exports are up.
