How soon are effects visible? Complete lack of food - days, chronic malnutrition - months or years. Lack of education - decades. Many people are not smart enough to think that far ahead.

Lack of education is also generally desirable to many people in power. Not just politicians who can more easily lie but also managers and execs. If the tax system is beyond most people's understanding, rich people are not gonna get taxed properly. If people can't do the math on how much value their work produces for a company, they are not gonna understand how big a chunk the people above them in hierarchical structures (like most companies) take out of it.

Unlike food, education (or lack of it) doesn't have universal definition. Because of that it's easy to stretch and manipulate. And it's been stretched and manipulated all the time cause possibility to indoctrinate young people creates immense political power. Like with free speech, non-uniform, not strictly state controlled (which implies private) education is a way to prevent state bureaucracy to concentrate too much power. That's not touching the fact that state hierarchies are well known for their inefficiency. Let's be fair, the reason people usually passionately bring education with politics in neighboring sentences is because it's widely accepted that our beliefs are right, and therefore people who stand against them are dumb, and maybe education can lead them (or at least their children) to our embrace! Funny thing, those "our beliefs" are often incompatible, and even opposite. Which makes me think that humanity doesn't work like that really
