I think this is the sort of things the original US leaders had in mind. After all just to vote you had to be a landed white male. They thought you needed something that they (the landed white males) regarded as a sign of substance in order to lead all the others, including women. The result of the system they put in place was to eventually give the vote and other rights to more, not fewer.
That said, I'd like to see the government of this country (USA) run according to the constitution for once. It's the political system, not the law that is hurting us. I'd say not enough people are allowed to vote. Not enough people have access to office. I say the vote isn't fair enough yet. As was shown in 2000, the vote can be taken from all the people.
And there are plenty of very intelligent people who will never have access to office in our two party system as it stands.
Why worry about IQ which is another system of control like the tests once given to blacks to keep them from voting? What about education? If we could educate ourselves decently, we'd be much further ahead. I guess this is an easier solution, because we've given up on education.
People don't use their heads to vote anyway. What are you talking about?
If you are going to use draconian measures, how about REQUIRING THAT EVERYONE VOTES (they may vote for "none of the above") and that they do SOME sort of civil service at SOME point in their lives? As it is, only a fraction of citizens take part in the government. The only thing we are required to do in regards to government is fork over our money.
