Podcast Episode 22 - Bonus: European Defence, Readiness, and the New Economics of Security

In this bonus episode, SBAI’s Brian Digney is joined by Jonathan Dimson, Senior Partner at McKinsey & Company in London, for a focused discussion on how ageing populations are reshaping public spending priorities across Europe.

Jonathan explains why demographic change is a slow-moving but profound challenge, with Europe shifting from a model where around two working-age people support every one non-working person, towards a much more even balance. The conversation explores the implications for pensions, healthcare and long-term fiscal sustainability, particularly in pay-as-you-go systems where today’s workers fund today’s retirees.

The episode also looks at the broader spending pressures facing governments, including infrastructure renewal, defence, technology and welfare. Jonathan reflects on the limits of birth incentives, the potential role of automation and robotics, and the need for European economies to remain attractive, productive and profitable places to invest and build businesses.

Key takeaways include:

  • Ageing populations will place growing pressure on pensions, healthcare and public finances.
  • Pay-as-you-go pension systems face particular challenges as the worker-to-retiree ratio declines.
  • Birth incentives have had limited success in reversing demographic trends.
  • Innovation, automation and productivity gains may help offset some labour market pressures.
  • Governments face difficult trade-offs between welfare, infrastructure, defence, technology and fiscal sustainability.
