McCain and the "Strong" Economy

From Barack Obama:

Hard-working American families are anxiously trying to make sense of yesterday's disastrous economic headlines.
While they're trying to figure out just how hard the news will hit them and their savings, John McCain's advice seems to be: don't worry about it.

Right after a major global investment bank declared bankruptcy, and in the middle of the second-biggest Dow Jones drop this century, McCain told an audience in Florida that "the fundamentals of our economy are strong."

How can the fundamentals of our economy be strong when, just this year, 600,000 Americans have lost their jobs? When people are losing their homes? When health insurance is beyond the reach of an ever increasing number of Americans?
John McCain clearly doesn't get it.
