Requiring poor people to pay a hefty fee, which they probably don't have, to get a passport seems a fairly competent way to go about making sure poor people don't vote to me.
If I don't want poor people voting, then attaching a fee to voting doesn't mean I'm incompetent. It means I'm smart enough to know poor people don't have money.
By the way, I think all of this is horrible. Everyone should be equal before the law and should have their vote count without having to pay for that right. I'm just pointing out that this is a really good way to eliminate the vote of the poor.
In a functioning democracy, voting is sacred. It must be treated as THEE core, fundamental right of every person under its care.
To violate this sacred tenet should be immediate grounds for exile. If you can't respect the ONE CORE tenet, or are incapable of, then there is not space for you in this society.
