Government policy touches nearly every aspect of daily life, from the quality of the air you breathe to the rules that govern your workplace, your healthcare, and your retirement. This book, written with the assistance of artificial intelligence, offers a clear and accessible introduction to the ways in which public policy shapes your rights, your choices, and your long-term prospects. Working through the key areas of government activity, it explains how decisions made by legislators, regulators, and courts translate into practical consequences for ordinary people.
