That deserves a challenge. Many significant contributors to US GDP are long-standing (>100yo) firms. Ford (founded 1903), General Motors (1908), Walgreens (1901), McKesson (1833), IBM (1911), Kroger (1883), Boeing (1917), Wells Fargo (1852), General Electric (1890), Johnson & Johnson (1886), Phillips Petroleum (1917).

Or the large companies that are repackaged versions of much older companies, with lineage back to the 19th century. Exxon & Chevron, for example, trace back to Standard Oil (1870); AT&T and Verizon (from Bell, 1877), Dow/DuPont (1897 or 1802, take your pick), Citigroup (from Citicorp, 1812). Banking often goes further back: BofA (Massachusetts Bank, 1784), JPMorgan (Manhattan Company, 1799).

Moving cuts of the pie around is a shell game. For sure the US is less regulated than Europe, so labels change more often, but the old money doesn't.
