Mariana Mazzucato argues that achieving smart, inclusive, and sustainable economic growth requires a new role for government, moving beyond merely fixing market failures. Public policy must actively tilt the playing field toward desired goals, recognizing that growth has a rate and a direction. This involves setting ambitious missions that galvanize investment, innovation, and production across multiple sectors (like climate change or the moonshot), with government acting as a catalytic market-shaper, not just a de-risker.
