contract-consecrated subservient arrangements in the large-scale corporations which control the world economy

One should never enter a contract having hazard potential of not later being able to buy yourselves out of. Requisite to that is the obvious forethought and responsibility to not do business with and to argue against gigacorps, such entities being well known in all of history to escape and steamroll over everything and everyone, exactly as government does. Eschewing the development of such responsibility, destructive left ancom etc arise. Beyond a certain size influence power control enforcement etc... GovCorp are both identically very difficult to downsize, shutdown, and extricate from. The time to start doing that was yesterday, now you're a day late, and you gave them two more of your dollars since then, and you're still on their Facebook, watching their TV, etc. With each passing day it becomes more difficult to gain your freedom. Are you going to start Monday, or are you going to continue growing them against your freedom for another week.

No. The fundamental cause is overpopulation, its rate of replenishment well beyond overshot by consumption, period. Whether overpopulation, and any consumptive level therein, is caused by ideologies and marketing of Government and Religion, and or part of DNA, is irrelevant, every face of the planet is now populated occupied controlled and modified by humans, the great rebalancing will occur, and it likely won't be pretty.
