Of course, demand was very high, and demand outstripped supply,

It's a market economy. Apparently the demand for great coaches exceeds the supply, so of course the price of good coaches is going to be high.

In the big picture, the whole world at every level, micro, macro, physiological, psychological, material, economical, spiritual, all are a demand-supply problem.

There's not much you can do about (the prices). It's a political matter. Of course, supply and demand comes into it, but I don't think the war in Iraq or (Hurricane) Katrina has any particular effect on it.

We have to continue to use both low-tech and high-tech tools to assist our Border Patrol in patrolling this portion of terrain and protecting ourselves against people who want to sneak across.

You can do the math. Supply and demand.
