Plenty of people "do just fine in their lives" without knowing how to read. This is discussing how to "be an educated citizen", a far higher bar. An educated citizen: * can have an informed opinion about the NSA's definition of "collecting" information [0]. * when told "we need to make sure that this list of 100,000 URLs are all valid websites", doesn't respond "wow, we'll need to hire a big team". * can reason about…
I disagree. That is like saying that an educated citizen must: * have an informed opinion on current Emission standards * be able to change oil on their own car * could describe how a 4-stroke engine works Replace the computer with a car and you will see that what you consider basic knowledge is not basic to most people. They rely on experts for advice, opinion, and guidance.

Education of the masses was believed to be instrumental to avoiding tyranny of the majority which was a very real concern (especially since so many Founding Fathers came to America escaping religious prosecution as the minority faith). It's my personal belief that the difficulty in achieving "sufficient" widespread education ultimately shaped the decision to model America's self-governance after a Republic with non-elected checks and balances (included non-elected ones e.g. Judicial) rather than a more direct/representative democracy.
The pseudo-perversion of the Electoral College leading to highly correlated Executive Branch elections with the popular vote I think undermines this system and heightens the education requirement of the average citizen.
Also, on a side note, the lack of perfect information has significant effects on Economic systems leading to market externalities.
