16.5 Budgeting and tax policy  (Page 4/28)

Balancing the budget has been a major goal of both the Republican and Democratic parties for the past several decades, although the parties tend to disagree on the best way to accomplish the task. One frequently offered solution, particularly among supply-side advocates, is to simply cut spending. This has proven to be much easier said than done. If Congress were to try to balance the budget only through discretionary spending, it would need to cut about one-third of spending on programs like defense, higher education, agriculture, police enforcement, transportation, and general government operations. Given the number and popularity of many of these programs, it is difficult to imagine this would be possible. To use spending cuts alone as a way to control the deficit, Congress will almost certainly be required to cut or control the costs of mandatory spending programs like Social Security and Medicare—a radically unpopular step.

Tax policy

The other option available for balancing the budget is to increase revenue. All governments must raise revenue in order to operate. The most common way is by applying some sort of tax on residents (or on their behaviors) in exchange for the benefits the government provides ( [link] ). As necessary as taxes are, however, they are not without potential downfalls. First, the more money the government collects to cover its costs, the less residents are left with to spend and invest. Second, attempts to raise revenues through taxation may alter the behavior of residents in ways that are counterproductive to the state and the broader economy. Excessively taxing necessary and desirable behaviors like consumption (with a sales tax) or investment (with a capital gains tax) will discourage citizens from engaging in them, potentially slowing economic growth. The goal of tax policy, then, is to determine the most effective way of meeting the nation’s revenue obligations without harming other public policy goals.

As you would expect, Keynesians and supply-siders disagree about which forms of tax policy are best. Keynesians, with their concern about whether consumers can really stimulate demand, prefer progressive tax     es systems that increase the effective tax rate as the taxpayer’s income increases. This policy leaves those most likely to spend their money with more money to spend. For example, in 2015, U.S. taxpayers paid a 10 percent tax rate on the first $18,450 of income, but 15 percent on the next $56,450 (some income is excluded).
