Your idea puts a married man’s ability to vote in the hands of his wife. If she leaves, he is penalized.
I disagree with your premise.
However, I would also state that being a net taxpayer should be a prerequisite to vote. (We can haggle about whether government employees are net taxpayers, too!)
Yes. If a marriage fails, the man can no longer vote.
That’s not a bug; it’s a feature.
It’s not “penalizing” him. It’s maintaining the principle that government should be in the hands of people who are successful adults with an investment in the future. I.e., married men living with their children. No shack-ups. No welfare “moms.” No transient men living off women’s welfare checks.
The point of my proposal is that the basic unit of society is the functional family, not the failed family, and not the atomized individual.
