From Wasted Lives, by Zygmunt Bauman:
Since the beginning of modern times each successive generation has had its shipwrecks marooned in the social void: the 'collateral casualties' of progress. While many managed to jump onto the speeding vehicle and thoroughly enjoyed the ride, many others - less cunning, adroit, clever, muscular or adventurous - lagged behind or were barred entry to the overcrowded carriage, if they weren't crushed under its wheels. In the vehicle of progress, the number of seats and standing places did not as a rule suffice to accommodate all the willing passengers and admission was at all times selective; this is perhaps why the dream of joining the ride was, for so many, a sweet one. Progress was advertised under the slogan of more happiness for more people; but perhaps the need for fewer (and ever fewer) people to keep on the move, to accelerate and to climb those heights that once would have required a much larger crowd to negotiate, invade and conquer was what progress, the trade mark of the modern era, was in the last instance about.
