How was the rise of the modern conservative movement a reaction to the changes of the Sixties and Seventies?
The rise of the modern conservative movement as a reaction to the changes of the Sixties and Seventies represented a political response to the changes in United States politics in those decades. Demographic shifts to the suburbs and Sunbelt were one of the causes of the rise of the conservative movement in those years.
The conservative movement initiated in the United States in 1960 until approximately 1970. The conservative people wanted to lower taxes. Let's remember that elevated taxes were necessary for other administrations to promote and support public programs aimed to help poor people like The Great Society program impulsed by Lyndon B. Johnson. So the conservative movement in America did not approve the ideas of a government that had to spend too much and for that to happen, had to raise taxes.
