The problem isn't that the US industry shed skill staff, its that we didn't force a conservation program upon ourselves when we had the opportunity.  That's what we're paying for.
But now we need to find the stuff and its not there and we dont have the staff.

You are right though. A lack of Conservation is probably the biggest mistake in the history of western civilisation. Assuming that there are historians in a thousand years time, this is what they will nail us on.

Pity we couldnt see it coming when oil was 15 US a barrel...

Some people did see it coming, even when oil was a few dollars per barrel. They were universally ignored by those in power.
