As politicians and pundits in Washington continue to spar over
whether economic inequality is in fact deepening, in corporate America
there really is no debate at all. The post-recession reality is that the
customer base for businesses that appeal to the middle class is shrinking as
the top tier pulls even further away.
If there is any doubt, the speed at which companies are adapting to
the new consumer landscape serves as very convincing evidence. Within
top consulting firms and among Wall Street analysts, the shift is being
described with a frankness more often associated with left-wing academics
than business experts. ...
Investors have taken notice of the shrinking middle. Shares of Sears
and J. C. Penney have fallen more than 50 percent since the end of 2009,
even as upper-end stores like Nordstrom and bargain-basement chains like
Dollar Tree and Family Dollar Stores have more than doubled in value
over the same period.
