The two Arthur Schlesingers have proposed that US political history goes in cycles:
CYCLES OF AMERICAN HISTORY It alternates between:
- Liberal, reform, public purpose
- Conservative, retrenchment, private interest
They proposed that this cycle happens for various reasons, like:
- Sustaining reform in liberal periods requires a lot of effort, and that effort may seem unnecessary if some reforms had been successful or seemingly successful.
- Conservative periods produce problems that the ruling elites are unable or unwilling to address.
Peter Turchin in
Cliodynamics also finds evidence of long-term cycles, though mostly in longer-lived nations. He has collected a lot of data on various social indicators, and he finds these correlations:

PT used first-marriage age a measure of social optimism/pessimism, with younger meaning optimistic and older meaning pessimistic.
Here's a combined table of the Schlesinger and Turchin cycles:

- Prty Sys = what party system, a set of parties with distinctive platforms and constituencies. The first one had a switch from Federalists winning to Democratic-Republicans winning in Thomas Jefferson's presidency.
- Amend = periods with several Constitutional amendments, though these often overlap other periods.
- PT Long = height and slope in Peter Turchin's long cycle
- PT FS = his 50-year father-and-son cycle of periods of unrest. The US did not have one in the 1820's, and it is due for another one around 2020.
Where are we now?
The US is currently in Gilded Age II, and it has lasted longer than the previous one. There is no hint as to when another major burst of reform will happen. The Occupy movement seemed like the start of one, but it was rather successfully crushed.
