Gold Standard, Empire Prosperity, and Pre-War Wealth
The early 1900s represented the peak of the gold standard era. The purchasing power of money was extraordinarily stable across the major economies — British pounds, US dollars, French francs and German marks all held their value remarkably well. A professional's salary could support a comfortable middle-class life with servants, foreign holidays and investment. Yet for the working class, a dollar still meant basic subsistence. The 1900 US Census showed 38% of workers earned under $400/year — equivalent to about $14,000 today, for 60-hour work weeks.
In 1900, Andrew Carnegie's annual income was estimated at $23 million — equivalent to roughly $800 million in today's purchasing power.
