Problem-posing education does not and cannot serve the interests of the oppressor. No oppressive order could permit the oppressed to begin to question: Why?
Indeed, the interests of the oppressors lie in “changing the consciousness of the oppressed, not the situation which oppresses them”; for the more the oppressed can be led to adapt to that situation, the more easily they can be dominated.
Implicit in the banking concept [of education] is the assumption of a dichotomy between human beings and the world: a person is merely in the world, not with the world or with others…In this view, the person is not a conscious being (corpo consciente); he or she is rather the possessor of a consciousness: an empty “mind” passively open to the reception of deposits of reality from the world outside.

Leftism is about saying positive improvement is impossible and that there is no possible future. The more you say that, the more leftist it is.
diminishing returns on resources and effort put into environmental cleanup is hardly “positive improvement is impossible”.
we can clean up a lot, certainly more than capitalists ever would but
is a ridiculous proposition even with global communism, and saddling future generations with our problems seems like a shitty thing to do to them.
So your not ridiculous proposition for global communism is no further generations to saddle whatsoever.
