That is hardly a feature of a place that offers “more economic opportunity than any nation ever.”
Tax revenue as a percent of GDP is between 15-25% constantly.
It’s the economic opportunity that affords 60% of tax returns to pay $0, the giant welfare state and $200,000,000,000,000 debt/unfunded liabilities while the US dollar is still unparalleled king of earth with no competition even existing. The Euro barely made a dent.
The biggest difference between then and now is wealth actually mattered. Electricity, indoor plumbing, superior medical care, cars and on and on. These days doctors are largely educated the same, we eat the same food, everyone owns the modern conveniences....wealth in America is largely banal.
