Relentless (Found)

The cause for the
slight progress is
to be found
                                                  in
a series of fateful events
which struck like a
relentless broom
                                                 ,
tearing down the web
of enterprise again
and again
                                                 .
And like industrious spiders
the promoters rebuilt their schemes
upon the same foundations.
