Why was it possible for a man in the 1960s to have an ordinary job, a family, and a house? Was there some hidden sector of society that suffered considerably more then now? Is there some sector of society now that prospers proportionally more at the expense of others?
The answer that immediately springs to mind is that women, ethnic minorities, and the urban poor all did relatively badly in the 1960s. With the latter two categories, for every apple pie home with a sedan and two kids there were umpteen other drafty tenement flats with malnourished families sharing a bedroom:

It’s not one thing or another — many factors have contributed to what feels like change this way or that over the years — but I try to never forget just how abominably crap life used to be for quite a lot of people, and just how much better it is these days.
