Depends on what you consider &quot;social engineering&quot; really. Even Hayek didn&#x27;t think that a developed market economy providing a social safety net (and levying taxes to pay for it) counted.<p>Khmer-Rouge style social engineering involved concluding the problem with modern economies is that people are choosing to work in industries not in the national interest, and a practical solution is to abolish all markets and use the military to relocate people and assign them new roles. Name one modern economist who has reached remotely similar conclusions.
