What we are witnessing is the human wreckage of a great historical turning point, a profound change in the social requirements of economic life. We have come to the end of the working class.
We still use “working class” to refer to a big chunk of the population—to a first approximation, people without a four-year college degree, since those are the people now most likely to be stuck with society’s lowest-paying, lowest-status jobs. But as an industrial concept in a post-industrial world, the term doesn’t really fit anymore. Historian Jefferson Cowie had it right when he gave his history Stayin’ Alive the subtitle The 1970s and the Last Days of the Working Class, implying that the coming of the post-industrial economy ushered in a transition to a post-working class. Or, to use sociologist Andrew Cherlin’s formulation, a “would-be working class—the individuals who would have taken the industrial jobs we used to have.”
The difficulty arises from few different factors:
- Culture
- Religion
- Geography
- Politics
Europe and Asia are actually one continent, but it has been 'divided' into two continents because of the reasons mentioned above.
Geographically are used some points as zone of separation, but there's still discussion which of the two prevailing is the most relevant.
From cultural and religious point of view Europe and Asia are mostly divided at the border of the Christian and Muslim world, but not totally, which also makes confusions.
And for last we have the political factor, where the geopolitical interest makes superficial borders as zones of interest, and thus making imaginary border lines.
