Concentrations of energy are what lead to wealth disparity–some people “own” businesses and capital goods, and some people (but not others) receive advanced education or other specialized training. All of these things allow a relatively small number of privileged people to receive a greater share of the output of the economy. This leaves less for the rest. As the result of this wage disparity, the economy ends up with too many people either dropping out of the work force, or earning low wages.

Gail Tverberg being vivid capitalism warrior, warrior for zoological, animal individualism, finally found the cause for all problems - wrong energy behaviour. :-)

Worst even, she like drunk captain in panic assume all people in the crew to be sharing her values and interests, so they just willingly want to vanish with capitalism intact.
