This book argues that the true competition between the United States and China is not over geopolitical dominance, but over who can more effectively resolve the internal contradictions of capitalism. As both nations face mounting economic and technological pressuresfrom artificial intelligence and smart automation to biotechnology and global inequalitythis provocative work reframes the US-China rivalry as a common struggle to transcend capitalism itself.Rather than portraying China and the US as ideological opposites, the book reveals how both are navigating the same systemic crises. It revisits the once-dismissed slogan "Only socialism can save China" and reexamines China's transformation from Maoist socialism to marketdriven growth. While China's post-Mao development model sparked an unprecedented economic boom in world history, it also deepened the country's entanglement with global capitalism, raising urgent questions about its future direction.Combining economic analysis with insights into technological disruption, the book offers a compelling rationale for socialismrooted not in ideology, but in the material realities of our time. It foresees a post-capitalist era in which global leadership is defined not by dominance within capitalism, but by the capacity to move beyond it.
