Answer:
C. Reagan’s policies contributed to a decline in living standards for the working class.
Step-by-step explanation:
When President Reagan was trying to break the cycle of stagflation in the U.S, he needed to raise interest rates, and borrow money. Suddenly, this lead to a recession, When he took office in his first year, bankruptcies grew, and unemployment reached its highest level since the Great Depression. Homelessness increased and the economy didn't recover until 1983. During Reagan's second term, he tried to help by giving $3.6 Billion in tax relief to families with incomes of $200,000 or more, but it was impossible to achieve.
So, that's why the living standards for the working class was declining during Reagan's administration.
