Quotes from Campbell McConnell

Savings, remember, is the prerequisite of investment.

economists recognize that, other things equal, cuts in tax rates reduce tax revenues in percentage terms by less than the tax-rate reductions. Similarly, tax-rate increases do not raise tax revenues by as much in percentage terms as the tax-rate increases. This is true because changes in marginal tax rates alter taxpayer behavior and thus affect taxable income.

economic growth is driven by supply factors such as improved technologies and access to more or better resources.
