The real threat to liberal democracy isn't autocrats - it's the lack of effective action by progressives. Here, two expert journalists reveal the structural, economic and political forces that have shaped the liberal world, and America, of today: where scarcity and preservation drive the agenda, and we no longer deliver on big ideas. Decades of slashing immigration, off-shoring manufacture, preventing house-building and stalling ambitious projects means America has a shortage of workers, houses and climate-change solutions. It's a story repeated across the Western World. To progress on the greatest challenges of our time, progressives need the vision, ability and willingness to enact transformative strategies. Here, the authors lay out the barriers, and how we can take to consequential action to build a future of abundance.
