“The fifth problem: peak capital”

The industrial capital stock grows to a level that requires an enormous input of resources. In the very process of that growth it depletes a large fraction of the resource reserves available. As resource prices rise and mines are depleted, more and more capital must be used for obtaining resources, leaving less to be invested for future growth. Finally investment cannot keep up with depreciation, and the industrial base collapses, taking with it the service and agricultural systems, which have become dependent on industrial inputs.

When do we expect peak capital to occur? According to the “standard run” of the LTG report, it may arrive during the first two decades of the century. It may very well be that much of what we are seeing now is a symptom of peak capital approaching: airports, roads, bridges, dikes, dams, and about everything that goes under the name of “infrastructure” are decaying everywhere in the world. The whole economic system is becoming unable to maintain the level of complexity that it had reached just a few decades ago.
