This set off the greatest period of wealth equality in the US, through a combination of factors:
- Strengthening the power of the Federal Reserve to re-liquidate banks.
- Direct government employment of individuals, whether through the Works Progress Administration (WPA), Civil Conservation Corps (CCC), and eventually of course the armed forces as the US entered WWII.
- Enormous strengthening of labour rights and unions within the US.
- The US stepping in as the world's leading manufacturer in the post-war era, having its industrial plant intact, raw materials available, and demobilisation providing for a vast increase in the labour force itself without wage reductions.
- Generally progressive policies in government regulation, civil rights, educational access, housing access, transportation improvements, and healthcare over the period 1945 -- 1975.
- A highly progressive tax policy.
Not all of that is obviously replicable today. The US faces strong disadvantages relative to other countries in raw manufacturing (though can produce very-high-value goods which make up in trade value what they lack in sheer tonnage) and demographic challenges (along with much of Europe and advanced Asian countries, notably Japan, Korea, and China). But other options remain available and to my mind useful. Changes in tax policy to re-distribute aggregated wealth and make tax havens (both onshore and off) far less viable would likely be good starts. These are of course politically challenging, particularly under present circumstances, but might remain within possibility.
