Maybe those who didn't graduate shouldn't get to vote?

Presuming that you yourself have "graduated" (what from is unclear), it's particularly audacious that you make this claim because it shows rather cleanly how poor a marker of quality an education is.

The answer has never laid in ever more elaborate designs to disenfranchise particular members of the population. It's always been in building community.

A community is what helps stabilize, helps tighten up distributions, and wrestles most authentically with the general premise that we are social creatures and only as strong as our weakest link.

If you think you're going to build the perfect society by way of careful electorate curation, I have some unfortunate stories to tell you.
