What I think the world needs now is for people to be better educated and have better critical thinking skills.
Couldn’t agree more.
Populations that can think critically are harder to manipulate and control by oppressive leaders.
Not as true. Consider groupthink, Kuhnian paradigm shifts (which, while largely non-existent in their most popular formulization do characterize how a majority or at least a large minority of experts in a scientific field can reject most or all of the theoretical framework within which they work for reasons that have nothing to do with science. Two examples that spring to mind are:
1) the almost complete abandonment of what was considered the “science” of eugenics, defeated not by scientific inquiry nor empirical findings but due to the horror induced by the holocaust.
&
2) The adoption of the biomedical model in psychiatry with the concurrent and causally linked publication of the DSM III.
Actually, perhaps the best example is Gödel. Almost certainly the greatest logician of all time, and he died of starvation surrounded by food in part because of his analytic prowess. His premise was that people were trying to poison him and he could only trust his wife to prepare meals, so when health required that she be hospitalized for an extended period he didn’t eat. He reasoned that, given others were trying to poison him and his wife wasn’t around, he couldn’t trust anybody (and was unable himself) to prepare meals, so he could either risk death by waiting for his wife’s return or ensure it by eating meals. He logically chose the former, and died.
Populations that can think critically are harder for big business and corrupt politicians* to hoodwink.
True (well, technically only if they
do not if they
can but that’s rather trivial).
Better educated people will make better choices in regards to being good stewards of the planet. And so on.
It is a mistake to equate education with critical thinking skills. Certainly, there is a correlation with higher education and tests/experiments intended to test critical thinking. However, there is also a stronger correlation between SAT scores and GRE scores, despite the fact that the tests do not differ qualitatively.
Cognitive scientists have learned that all cognitive activity uses the same supply of glucose.
No we haven’t. We have demonstrated that this isn’t true, and pretty fundamentally untrue, as so basic a divide as intra- vs. inter-neuronal glucose levels is required to model action potentials.
Everything you do with your brain, drains the same "fuel tank".
It doesn’t. A simple counter-example would be neurotransmitters, which are essential to cognitive functions (though I believe I get what you are saying; you’re using the same “fuel” metaphor we find with “calories” and the body). The entirety of fMRI studies rely on using (de)oxygenation as a proxy for neural activity, the mechanisms which govern neuronal spike trains are intra- vs. extracellular charges, and glucose isn’t the only “fuel” source.
Even something as simple as exercising willpower uses brain glucose.
I’ve been a researcher in neuroscience for a relatively short time (less than a decade), but the fact that I’ve never come across any study even referencing some study in which this is true (along with the fact that we don’t actually use notions like “willpower”) makes me wonder whence comes this claim.
As an anti-theist, I see the mental energy the "faithful" put into keeping their religion plausible. I have to think that religion overall (even moderate religion), works in opposition to increasing critical thinking.
Not critical thinking, but perhaps cognitive “load”
"the data show that while believers strengthened their beliefs, non-believers wavered from their disbelief. This pattern is more consistent with a “distinct cognitive inclination” account of supernatural belief (Norenzayan & Hansen, 2006, p. 183), in which human beings are naturally and uniquely attracted to belief in supernatural agents."

"Cognitive and evolutionary theories of religious belief highlight the evolved cognitive biases that predispose people towards religion. Although there is considerable and lively scientific debate, one widely discussed view holds that disbelief, when it arises, results from significant cognitive effort against these powerful biases. According to this view, if the mind-perceiving and purpose-seeking brains of human beings effortlessly infer the existence of invisible agents with intentions, beliefs, and wishes, then disbelief lacks intuitive support. Therefore, atheism is possible, but requires some hard cognitive work to reject or override the intuitions that nourish religious beliefs"

"Despite these uncertainties (or perhaps because of them), the one apparent consensus among the commentators is that atheists are best accounted for by Hypothesis 2 (Natural Variation): atheists are simply one end of a continuum of belief. On the face of it, this is unsurprising, even an anti-climax. Like numerous other traits in nature, beliefs vary - so what? However, if this is true, then there are in fact several striking implications. First, it implies that the mean of the distribution is some positive level of religious belief (that is, there is a consensus that natural selection has favored cognitive mechanisms underlying belief, and/or religion itself). Second, it implies that atheism is (or was) a suboptimal strategy for human beings. Third, it implies that atheists - given their status at the tail end of the distribution - are (or were) selected against."

Perhaps religion does have some benefits (I'm not convinced), but whatever benefits religion might claim, it strikes me that these benefits could be provided without the need for cognitively draining, supernatural explanations that fly in the face of an otherwise honest view of the world.
All the evidence indicates non- or disbelief is “cognitively draining.” Meanwhile, the sciences are largely the product of religious inquiry (the university system was, after all, a product of the church).
