There are two groups of households in an economy: groups 1 and 2

Group 1: High income families. MPC is about 0.1

Group 2: All other families. When they lose their job, they reduce spending. MPC is about 0.8.

The government can cut taxes by $200 billion or increase transfer payments for some or all of the other families. Both programs cannot be done, and both cost $200 billion per year.
