Population aging is often met with calls for more immigration, but I've yet to see solid evidence that it truly reverses the fiscal strain—newcomers also age, and integration costs money upfront. My own country's experience suggests we're just kicking the can down the road, with social security systems still under pressure. Maybe we need to rethink retirement ages and productivity gains instead of relying on demographics to save us. What's your take on the real fix for the aging population challenge?
