What is the central theme of the passage

Rage against the machine is the main theme. The times are changing for extended members of the Brangwen clan. The canal cut into their property to connect the collieries is a symbolic slashing of tradition and convention. The days of bucolic individuality are about disappear as the Industrial Age makes its way out of the cities and into the gentry. The factory is an appropriate metaphor for what amounts to a wholesale change in a society seeking to transform the individual into the collective. This machinery of homogenization extends from the collieries to the school where Ursula unhappily teaches to the formulated geometrical layout of the industrial towns growing up to give the colliery workers a place to live; a place that feels the regimented order of the workplace. The Brangwens rebel in general, but Ursula’s rage is expressed the most fervently.
