Instead of limiting who can vote, a better solution would be a government that couldn't tax our productivity in an uneven manner, thereby redistributing my precious and limited time on this Earth to other people. In lieu of that, however, the next best solution is to limit voting to those who materially participate - and to strip it from those who are merely along for the ride. What that looks like specifically can be debated, but the philosophical point some have made on this board is pretty clear.
I admit it's a re-imagining of our idea of "democracy," but then again, so is the fact that 40+% (nearly 50%) of my time is stolen from me in some form or another and "redistributed" to other people. That's not the system any of us signed up for either. Rather, it's the end result of a perpetual creep from our originally envisioned government instituted to help us secure our life, liberty, and happiness. For a long time, voting was the best means to guarantee everyone's collective, long-term goals. Now it's become a means by which certain groups use the government to disenfranchise other groups. Voting ain't it anymore. Voting is a nice-to-have. Voting is a mechanism, it's not fundamental to a good life. A good life is me being able to keep what I produce. As soon as voting has become the way whereby I'm made a slave to other members of society, it has ceased being a necessary part of our society. We're all familiar with the meme about two wolfs and a sheep voting on who's for dinner...that's where we are and where we've been for some time.
You have millionaire SS recipients who take 12.4% of my wages and spend it on whatever, instead of selling their million-dollar homes. Instead, they're going to deed their estates to their heirs, and use my wages to bridge the gap to their end-of-life. 12.4% of my time enables old people to make choices they otherwise couldn't (or wouldn't) make. In a two-week period of Mondays through Fridays, that's (more than) one whole day of my time. My commute. My gas money. My wear and tear on my vehicle. My time I could spend doing whatever else I want to do. Instead, my time is spent going to work for the retired. 30% of my income to income taxes? Well, you can do the math on how many days that takes up.
You have EBT recipients who use their benefits to purchase luxury goods. You have school lunch recipients who throw away literally 100% of the food they receive into the trash. Every. Single. Day. Again, that's my time being thrown into the (literal) garbage can.
The examples go on and on and on.
I don't lament people's shock and disbelief that people could advocate for something as seemingly undemocratic as taking away people's right to vote. I understand those beliefs rest upon a hopeful, childish, but ultimately naive view of how our government and society function. i.e. a view grounded in a high-school-civics-level conception of our society. It only seems gross when it's juxtaposed against the cartoonish view of what we're programmed to think. When it's held up to a holistic view that encompasses how money, time, and productivity are actually redistributed throughout our society, it's the obvious answer.
