The policy that a government might use to redistribute income from high-income earners to low-income earners among the options provided is the negative income tax.
A negative income tax is a system in which individuals earning below a certain threshold receive supplemental pay from the government instead of paying taxes, effectively transferring wealth from higher-income earners to lower-income earners.
While food stamps, prescription drug coverage, and free and reduced school lunches can also assist low-income individuals, they are not direct methods of income redistribution in the same way as a negative income tax.
