Modernism failed from too much faith in planning, not from market subordination.

Evidence

For the ultimate error of modernism, he explains, was not so much lack of vigilance towards the market, as too much trust in the plan. Not the commands of capital, but necessities of modernity — the structural differentiation of society, rather than the pursuit of rent or profit — condemned it to frustration. ‘The utopia of preconceived forms of life that had already inspired the designs of Owen and Fourier could not be realized, not only because of a hopeless underestimation of the diversity, complexity and variability of modern societies, but also because modernized societies with their functional interdependencies go beyond the dimensions of living conditions that could be gauged by the imagination of the planner’. — Perry Anderson, The Origins of Postmodernity, 94

Categorization

• DEEPTHINKING: Inverts the standard Marxist indictment of capital as the cause of modernist urban failure — locating the fault in the plan itself, a genuinely counterintuitive causal claim.
• XREF: connects to: Modernism’s decline stems from political defeats rather than economic change — Perry Anderson, The Origins of Postmodernity, 216; Modernism’s radical promise failed because culture cannot independently transcend its social and economic conditions.; Postmodern architecture rejected utopian planning in favor of market-driven spontaneity — Perry Anderson, The Origins of Postmodernity, 59
