What did the economic problems in the early 1970's illustrate?

The economic problems of the early 1970s, characterized by stagflation—simultaneous high inflation and unemployment—illustrated the limitations of Keynesian economic policies that had dominated post-World War II economics. These issues revealed the challenges of managing a mixed economy facing external shocks, such as oil price hikes and shifts in global trade dynamics. Additionally, they marked a pivotal shift towards more market-oriented policies and a reevaluation of government intervention in the economy, ultimately leading to the rise of neoliberalism in subsequent decades.
