Economist: Countries with lower tax rates tend to have stronger economies. Although higher taxes raise more revenue, highly taxed consumers have less disposable income. An economy can never grow if consumers aren' t able to purchase goods and services. Ttherefore, the government should lower tax rates across the board. The economist's argument depends on assuming that: ['Economic growth is more important than supporting social welfare programs.', 'Lower tax rates will be much more popular with consumers.', "Consumers' disposable income is directly related to their ability to purchase goods and services.", 'Increasing disposable income is the only way to ensure economic growth.']
