Suppose that a society is made up of five families whose incomes are as follows:
$120,000; $90,000; $30,000; $30,000; and $18,000.
The federal government is considering two potential income tax plans:
Plan A is a negative income tax plan where the taxes owed equal 1/3 of income minus
$20,000.
Plan B is a two-tiered plan where families earning less than $35,000 pay no income tax
and families earning more than $35,000 pay 10% of their income in taxes. The income
tax revenue collected from those families earning over
$35,000 is then redistributed equally to those families earning less than $35,000.
