The wealth gap is provoking much contemporary anxiety. But the financial imbalance between, say, Bill Gates or Warren Buffet and the Big-Mac slinger is a shadow of that which existed between the first American capitalist barons and those at the bottom of the heap. The US was developing like a runaway train, taxes were low, labour laws and financial regulation were almost non-existent and concern for the environment was an alien concept.
The fortunes amassed were truly staggering and few, if any, were bigger than that accumulated by W.A. Clark between 1860 and the 1920s. Today he would be called an entrepreneur. He graduated from buying and selling eggs to miners to owning huge chunks of America's copper reserves, building railroads, running banks and being involved in the founding of Las Vegas.
At the height of his success he built the most costly mansion in New York: a 121-room fantasy so expensive that he won a huge reduction in local tax on the grounds that it was unsaleable. No one else could afford to run it. And he was right. It lasted less than 30 years.
But this extraordinary piece of real estate was only one in the property portfolio of Clark and his heirs. His second wife, Anna, and his daughter, Huguette Clark, continued acquiring residences of breathtaking opulence. One of them, Le Beau Chateau in Connecticut, caught the attention of reporter Bill Dedman who discovered that it had been empty but maintained for over 50 years.
Further investigation revealed Huguette's prime apartments in New York and another unoccupied mansion occupying 9ha of Santa Barbara clifftop in California. This too had been unoccupied for more than 50 years but had been kept in pristine condition.
