Very well articulated adn summariex. As a European, it is not the case that tehre are no struggles. The focus on social democracy has taken a toll on keeping pace with innovation and modernization.
The interesting next step for social democracies will be to find a way to keep pace with innovation to play a prominent role in the external changes to climate, AI, new forms of economic and societal activities that are emerging. Just because social democracy has won over liberal democracy does not mean that the journey has ended - it is just shifting towards new challenges that Britain and America have yet to have time facing.
