If you laid all the economists end to end...

...they still couldn't reach a conclusion.

Nobel Laureate Paul Samuelson warns us that we have to address our long run borrowing before it causes financial Armageddon:

Up until now, China has been willing to hold her recycled resources in the form of lowest-yield U.S. Treasury bills. That's still good news. But almost certainly it cannot and will not last.

Some day -- maybe even soon -- China will turn pessimistic on the U.S. dollar.

That means lethal troubles for the future U.S. economy.

When a disorderly run against the dollar occurs, I believe a truly global financial panic is to be feared.

But Nobel Laureate Paul Krugman thinks it is too early to start saving:

To sum up: A few months ago the U.S. economy was in danger of falling into depression. Aggressive monetary policy and deficit spending have, for the time being, averted that danger. And suddenly critics are demanding that we call the whole thing off, and revert to business as usual.

Those demands should be ignored. It’s much too soon to give up on policies that have, at most, pulled us a few inches back from the edge of the abyss.

And now President Obama wants us to spend now on Medicare because it will have a long run benefit:

MEDICARE expenditures threaten to crush the federal budget, yet the Obama administration is proposing that we start by spending more now so we can spend less later.

This runs the risk of becoming the new voodoo economics. If we can’t realize significant savings in health care costs now, don’t expect savings in the future, either.
