How about saving existing jobs? The loan to Detroit automakers is a step in the right direction, but much more is needed.
We can do this with "Medicare for All" a k a single-payer. Medicare for All would help re-capitalize business (especially manufacturing), school districts, state and local government, individual payers and the under and uninsured. The states would use any excess of savings for unemployment and pension funds. Overall, this could save hundreds of thousands if not millions of jobs, while putting money quickly and directly into the system in the most efficient, fairest way: taking care of people's medical bills.
Saving jobs is far quicker and less expensive than trying to create new jobs.
