The operational definition of intelligence is a consistent display of appropriate behavior. Behind the behavior is a mental construal of how the world works. Failing to comprehend the environment invariably has negative consequences. In the instance of humans on planet Earth, the diagnosis is clear and the outcome apparent. These creatures face impending extinction and are taking much other life out with them.
Capitalism creates exploitation opportunities at every turn. Capitalism has excelled at grinding the great mass of humanity into indentured servitude better than feudalists could have dreamed, all the while placating by dangling the false hope that “you too can strike it rich.” On top of that, in less than 200 years since the onset of the Industrial Revolution, capitalists polluted the world at a pace to create the Earth’s sixth major extinction event, with zero prospect of reversal. That’s progress.
Humans excel at getting polluted, in every sense. Industrial pollution got raised to a new level following the second World War. The so-called “baby boom” generation of the 1950s were the first to get seriously POPed: exposed to a continuing dose of persistent organic pollutants. They are now paying the price of “better living through chemistry.”
