Klein and Thompson argue that America’s liberal approach – cantered on distribution, regulation, and procedural caution – has led to a stagnation that impedes housing, infrastructure, clean energy and innovation. They propose an ‘abundance agenda’ that flips the script: streamline zoning and environmental rules, prioritise big public investments, and embrace technological breakthroughs to actively build a future of affordable homes, green energy, better healthcare and efficient transport. Drawing on global case studies like Houston’s minimal regulation growth and critiques of slow-moving systems such as California’s high-speed rail, the authors call for a pragmatic, yet visionary liberalism focused on tangible outcomes instead of perfection of process.
