This company coal town in Iowa was a 'black utopia'

Frida Ghitis: Buxton , Iowa , was built by the Consolidation Coal Company , a coal-mining company town.

She says the town was built around a single industry that had many effects, including social gap between the people who ran the mines and everyone else.

Ghitis says Buxton 's story offers an important reminder: If you want a community to last, don't put eggs in one basket.
