Whatever the effort to manipulate the price, all the big easy to pump
oil fields have been found. The diligence of the search proves that.
What new oil being found now is increasingly hard to get. Crunch the
numbers; The amount of oil it take to find more oil is increasing, and
the size of the reservoirs has been declining.

A: And as the price rises, the greed rises. With the greed comes
violent efforts to control a supply, and that violence damages the oil
infrastructure so that there is a net decline in production. Which
drives up the price. Goto "A:"

Most hominids did not evolve in the nuclear family, but the manor
house, the village, & the tribe. The nuclear family was not invented
for the common man, but the elite to regularize the inheritance of
power and wealth. Even at that, the men were rarely monogamous.

The singular example of the nuclear family found by archeology is the
Slavs, who were despised because the families were dominated by women,
and the men could not be organized into effective armies. While their
lifestyle clearly predates the 5th century, it is here, at the end of
the Roman empire, when there was a vast no-man's land along the
fontier that had been devastated and abandoned because of all the
violence.

The farmland had grown up in brush like an old clearcut. Stepping into
it, you could hardly see 20 meters in any direction. Slav couples came
in, dug out a low profile earth bermed tiny cabin, and with Roman
tools, cleared a garden and built a life hidden away in the bush.

It didnt matter how big & strong Slav men were; a wife could easily
run away into the bush and never be seen again. There was no alpha
male power structure to deter her. Its a pattern that has existed in
various parts of Europe for millennia. The couples who were competent
parents had children survive. Those that didnt needed the case
management of witches, shamen, and elders in some community to provide
the welfare to raise the next generation.

Either way, in the tiny cabin or the communal longhouse, the carbon
foot print/capita was way lower than seen in the American Middle Class
lifestyle. If that lifestyle is no longer affordable, then most women
will return to the communal model. The price of commodities, like oil,
is driving the culture in that direciton.
