In career essentials what is the best definition of a progressive tax system?

A progressive tax system is one in which the tax rate increases as an individual's income rises. In this system, higher earners pay a larger percentage of their income in taxes compared to lower earners, thereby aiming to reduce income inequality. The structure typically involves multiple tax brackets, where each bracket corresponds to a specific income range and tax rate. This approach is designed to ensure that those with greater financial resources contribute a fairer share to public revenues.
