According to the textbook, looking ahead to the future of federalism, why are population aging and the rising costs of healthcare increasingly putting pressure toward greater federal government spending? Unless something is changed, the national debt will continue to grow. How are Republicans and Democrats currently differing in their approaches to this challenge?

US has the highest healthcare costs Republicans oppose tax increase while Democrats favor a mix of moderate spending cuts and significant tax increases

Explanation:

The United States spends about twice as much on health care as other rich countries because everything from drugs to equipment to doctors' pay is more expensive, according to the textbook "Looking Ahead to the Future of Federalism." As the population ages, more medical care is needed and this care results in the need to create more hospitals, medical schools, equipment, professionals, among other things that cause the US to incur high healthcare costs.

National debt is a term that refers to all debts contracted by the federal government to finance its budget deficit, including refinancing its own debt, and for other specific purposes, as defined by law. This debt is paid through tax-collected money, ie public money. Experts believe that national debt will continue to grow. Republicans and Democrats differ on how public money should be collected to pay off these debts. On the one hand, Republicans are strongly against raising taxes to pay government debts. On the other hand, Democrats believe that not only will tax increases be necessary to reduce debt, but also a series of government spending cuts.
