Generation X is officially 1966-1976 so I reckon probably that's the tail end of all the post war goodness. Starting out with music like the Doors, and ending in the punk explosion and the kick back of the establishment. Then on into the Thatcher years, the free market, the poll tax riots, and then moving on to full on wealth creation, coke, social mobility, a so called meritocracy, and then freedom of personal choice. With the edge coming off by producing boring socially conformist kids who live on Facebook.
