The problem is not that people don't want to vote, it is that people can't vote: voter suppression (e.g. voter roll manipulation, ID requirements abused to specifically target PoC) or people working two/more jobs combined with the fact the US unlike almost all other countries do not vote on a Sunday or have it a national holiday are quite powerful.
To add to that mix, mail-in voting is not accessible by default for everyone, and extreme gerrymandering (local/state elections) and the "electoral college" system (presidential elections) make it effectively moot to vote in states that are either hard blue or hard red.
