In this devastatingly witty new book, Carl Cederstr m traces our present-day conception of happiness from its roots in early-twentieth-century European psychiatry, to the Beat generation, to Ronald Reagan and Donald Trump. He argues that happiness is now defined by a desire to be "authentic", to experience physical pleasure, and to cultivate a quirky individuality. But over the last fifty years, these once-revolutionary ideas have been co-opted by corporations and advertisers, pushing us to live lives that are increasingly unfulfilling, insecure and narcissistic.

In an age of increasing austerity and social division, Cederstr m argues that a radical new dream of happiness is gathering pace. There is a vision of the good life which promotes deeper engagement with the world and our place within it, over the individualism and hedonism of previous generations. Guided by this more egalitarian worldview, we can reinvent ourselves and our societies.
