Mike Davis has a very good article on Tomdispatch arguing that while infrastructure investment is desperately needed in the US, keeping our existing public institutions like hospitals and schools operating should be top priority:
Yet saving (and expanding) core public employment is, hands-down, the best Keynesian stimulus around. Federal investment in education and healthcare gets incomparably more bang for the buck, if jobs are the principal criterion, than expenditures on transportation equipment or road repair.
For example, $50 million in federal aid during the Clinton administration allowed Michigan schools to hire nearly 1,300 new teachers. It is also the current operating budget of a Tennessee school district made up of eight elementary schools, three middle schools, and two high schools.
On the other hand, $50 million on the order book of a niche public transit manufacturer generates only 200 jobs (plus, of course, capital costs and profits). Road construction and bridge repair, also very capital intensive, produce about the same modest, direct employment effect.
