National Park Grade Inflation

The U.S. has promoted many lesser National Monuments into National Parks over recent decades, roughly doubling the roster since mid‑20th century, which dilutes the category’s prestige and may change funding, visitor expectations, and conservation priorities. That shift is comparable to 'grade inflation': more places get the top label even if fewer are uniquely spectacular. — If true, the trend reshapes what Americans consider 'national' worth preserving and affects tourism economies, federal land management priorities, and cultural meaning of national heritage.
