You are framing the situation as if there only would be two options; do nothing or pump trillions of dollars into financial markets. But there is a third option. Use those trillions of dollars to take care of the people hurt by the crisis. Provide unemployment benefits and free healthcare to the people affected. The money could also be used to fund a jobs guarantee program. For example, to construct a high-speed rail network or to build homes to solve the homelessness crisis.
