I suppose that eventually we will reach some world market price for natural gas like we have for oil, but I sure would love to see our relatively low natural gas prices lead a resurgence in US industry -- especially in the rust belt where this shale gas exists, before that happens.
All things considered, I'd rather be exporting value-added manufactured products rather than raw resources such as natural gas. Low energy prices would sure go a long way to make that happen.
Some of that is already going on.
