"It not only relies on foreign saving to fund domestic growth, but it also lacks the capacity to invest in public goods that may be needed to safeguard its future. Lacking in domestic saving, the shoestring economy is also biased toward chronic under-investment in infrastructure -- leaving itself vulnerable to "breakage." Whether that breakage comes from within (i.e., Katrina) or from the outside (i.e., terrorism), the shoestring economy runs the risk of being unprepared to ward off such blows in a fragile and dangerous world. An energy shock exacerbates the imbalances that produce such vulnerability. This draws into serious question the resilience that financial markets now seem to be banking on."
