Most common federal income tax deductions for individuals. Many of them could perhaps be classified as family-based deductions, or enacted deductions that target those who might have children or other types of family obligations to fulfill. Is there an underlying theme or purpose to most of these deductions? If so, what is it? Do the deductions that Congress has enacted advance this purpose? Is this something that Congress should be doing at all? Provide an example of two such deductions, and supplement your argument with outside resources discussing the pros, cons, and impacts of these deductions.
