Jeffrey Sachs, the Director of The Earth Institute at Columbia University, has sharply criticized both the Democrat and Republican approaches to dealing with our failing economy.

For instance, Sachs complains that President Obama is seeking to kick up consumer spending through “near-zero interest rates, massive Fed financing of mortgages and various consumption incentives, such as rebates for new home-buyers and cash for clunkers.”  According to Sachs, though this will simply get us into a new bubble, as the US consumer is encouraged to over-borrow.  This is a terrible strategy “with budget deficits of about 10 per cent of gross domestic product.”

How about those Republicans?  Their “solution” is equally terrible:

For every problem there is a single Republican answer: tax cuts. Simple arithmetic reveals the stunning shortsightedness of this proposition. The federal government collects about 17 per cent of GDP in tax revenues. That roughly equals the outlays on social security, Medicare, Medicaid, veterans’ benefits, defence and interest payments on debt.

All the rest – roads, rail, clean energy, science and technology, diplomacy, international disease control, space, education, job training, water, transport, courts, poverty relief, homeland security, conservation, climate adaptation – is financed on borrowed money. All of these critical areas are underfunded, which hinders productivity, national security and private investment.

What a good idea that is being largely ignored?  Sachs likes the idea of jump-starting the green economy:

One where the jobs would come through a massive expansion of low-carbon energy. We were told about plug-in hybrids, intercity fast rail and new water and sewerage plants to replace the crumbling infrastructure. We were told about a new infrastructure bank to fashion complex multi-state projects that would employ huge numbers of workers while building a cutting-edge economy.
