Personally I would guess that the >50% of eligible voters who don’t vote, largely due to systemic disenfranchisement, are a bigger issue.
Another systemic issue is FPTP.
I find any solution to “fix” democracy that attacks/criticizes the individual voter to be barely valid. The solution to a systemic problem is always going to be systemic in my experience.
