Taxes.
The tax burden in France, prior to the French Revolution, fell on the shoulders of the 98% of the population that made up the Third Estate. The First Estate consisted of the clergy, and the Second Estate was the nobility. Those two estates overlapped in some ways, because high ranking church officials functioned as a form of aristocracy too. And the two leading Estates colluded with one another to keep the system operating the way it was, with them having all the privileges and powers underneath the monarchy.
On January 20, 1961, the handsome and charismatic John F. Kennedy became president of the United States. His confidence that, as one historian put it, “the government possessed big answers to big problems” seemed to set the tone for the rest of the decade. However, that golden age never materialized. On the contrary, by the end of the 1960s it seemed that the nation was falling apart.
The United States' policy of containment wasn't just military, it was ideological. Back then, we pointed out the differences between Soviet Communism and Communism around the world to weaken the power of its rhetoric, and additionally we appeared to be more successful and had a better standard of living than communists. Today, we can point out the difference between Islamic terrorism and moderate Islam, to degrade support for Islamic terrorism and make it defeat itself by containing enabling states (as Islamic terrorism is supported by enabling states) perhaps via economic incentives,and stopping our support of dictatorships, winning over those in danger of becoming Islamic terrorists. We also built up a system of allies with our containment policy regarding the Soviet Union, which helped isolate the Soviet Union. We can build up support among allies to support us in isolating states that are enablers of Islamic terrorism as well.
