At the centre of my criticism is that these generations benefited from massive public investment in infrastructure and services. Post-war construction in the UK was essential, but in the United States this also involved the full development of Roosevelt's New Deal and the Keynesian economics that stemmed from the Great Depression, an approach to economics that also benefited New Zealand and Australia.
Boomers in the UK particularly benefited from the incredible social mobility that was the result. What annoys me the most, then, is when Boomers make claims about being "self-made" without any comprehension or recognition of the huge advantages they received from an economy boosted by public investment.
Gen Xers also benefited from the post-war consensus, but often look down on Millennials for their social compliance and instrumental thinking. Gen Xers like to think of themselves as rebels and punks who tore down the mask of 70s suburban civility, but in grand political terms, they did nothing.
Their revolt and dissent ultimately turned into a nihilistic morass of individual expression that Reagan and Thatcher turned into the free-market ideology of "choice". Both Boomers and Gen Xers wasted the post-war consensus and the collective desire for change that emerged in the three decades immediately after the war.
By the time Millennials were being born, Boomers and Gen Xers had voted in politicians who would begin to strip away social security, undermine public investment and any legitimacy there lay in dissent.
Boomers and Gen Xers produced a culture in which Millennials are expected to be compliant drones in an age when risk has been moved away from corporations and been placed squarely back on the shoulders of workers.
In this environment the right to an education has also been turned into the obligation to take on debt, and in every interaction Millennial are reduced to customers; not students, patients or citizens, just customers. Boomers and Gen Xers benefited from grants for university or from low fees in the US because the universities were not yet committed to maximising profits over education.
In my job as an academic I work closely with these young people and I find them incredibly positive, resilient, creative, hopeful and hard working. They deserve so much more than the paltry scraps left by Boomers and Gen Xers who have no idea how lucky they were.
From the perspective of today's young people, these previous generations have created potentially unlivable social and environmental conditions. From times of collective support, public investment and the legitimacy of rebellion, Boomers and Gen Xers have handed down environmental degradation, possessive individualism, instrumentality, pointless consumption, conformity, unnecessary war, plutocracy, growing inequality, rising problems in mental health and a culture of spite, and in my view, epitomise the blindness to privilege that so blights our culture.
