Money Talks: A shot in the arms

For decades fat defence contracts in America and Europe have been shared between a small number of giant contractors.

Guests: Steven Grundman from the Atlantic Council, a think-tank, and Brian Schimpf, co-founder of Anduril, a defence startup. Sign up for a free trial of Economist Podcasts+.
