Beavis and Butthead

For years, American television gave the world a surprisingly profound insight into the culture and sociological nature of the US. The television of the 1950s and much of the 1960s portrayed a contented nation at the zenith of its domestic wealth (for the time and in many ways beyond).
This mirrored the confidence of a country whose consumer product boom and geo-politically assured position, created a sense of invincibility among much of the population. Though exaggerated at the time, with hindsight, it is not difficult to see why such a cultural attitude developed.
