CURING A DEPRESSION
The Great Depression of the 1930’s was cured by the Government preparing for and then waging World War II. Millions of unemployed people got jobs and had money in their pockets to buy things that they hadn’t been able to pay for. Money flowing in all directions created prosperity.
The Government itself did not hire the millions of people --- it contracted with corporations and entrepreneurs to provide the goods and services. Those businesses then hired the workers. It was not the war itself that created the jobs, but the fact that Government was buying things.
This could be done now ---- not buying war supplies, but the things the country needs like improvements to the transportation system, increasing the capacity of the electrical grid and building many more renewable energy facilities.
