If the wealthiest people in the US had their own island, it would be the 5th largest economy in the world. Its citizens would be buyers of goods and services through good times and bad times. They would be the least impacted by tectonic shifts. They would be driven only by their own needs and desires.

During the first two months of the global pandemic, America’s billionaires saw their wealth increase by $434 billion, according to a report by Americans for Tax Fairness and the Institute for Policy Studies. That takes the net worth of America’s 600-plus billionaires from $2.9 trillion to $3.2 trillion. That puts them slightly ahead of the GDP of India.
If you could set up shop on that island, wouldn’t you?
