From an Australian perspective, my proposal is:

• Eligible to vote at 16.
• Compulsory voting at 18.
• A citizen’s vote has a weight of 100% until 20, then drops 5% at each birthday that ends with a 0.

The reason for the diminishing weight of a vote is to correlate with the diminished exposure political decisions will have on the citizen.

I think rhe voting age should be the lower of the minimum age to labor or the age of potential conscription less the age of the longest-term official whoss job includes sending people to war.

In the USA, that would put the voting age all the way down to 12. And having both been 12 myself once and having close family who were recently 12, I'm entirely OK with that.

Honestly I think everything should move to 20.

Alcohol purchase, consumption. Military conscription, draft, voluntary service Age of majority, marriageable age Voting with automatic voting registration Drug consumption including nicotine, caffeine, and cabinets Driving ( permits at a prior age with supervision )

We know people's brains aren't really formed enough even at 18 to consider people adults, this younger age is a hold over from even younger ages and doesn't reflect reality.

People who are not fully developed shouldn't be able to make decisions with the full weight of adulthood, to take any other position is barbaric.

20 - 55

I've wondered this ever since I was in high-school. What is the point of a political system I'm not even allowed to participate in other than cute photo ops? If they wanted people engaged in voting there would be no limit and everyone would be encouraged to vote. As to what age we count the votes? I doubt that any line you drew would ever be the deciding point of an election honestly.

America is in the business of preventing voting though, not encouraging it.

Between the ages of 25-55. Younger than that allowed by application only and they have to sit a test, to show they understand the basics of government.

Over 55s should not be allowed to vote.

En verdad no tengo problemas con la edad para votar actual.

Estoy convencido, como alguien ya adulto que pasó por la adolescencia, de que los adolescentes no tienen idea de que es lo que quieren en la vida, son muy volubles y manipulables y no es hasta que llegan a la adultez que pueden empezar crearse una idea de cuáles son sus ideales politicos. Vamos, incluso los adultos no lo tienen muy claro hasta que están más cerca de los 30 que de los 20, pero aumentar la edad de votación hasta las 30 o más sacaría a muchos de votantes de la ecuación, la mayoría de ellos gente con ideas progresistas.

Los 18 quizá no sea ideal, pero es aceptable. Hablas de Greta, por lo que he leído recientemente ella a sus dieciocho ha madurado aún más sus ideas, dándose cuenta de que los problemas son más sistemático, algo de lo que quizá no era consciente a sus 16. En lo personal, hay un montón de cosas que no consideraba a mis 16 que no fue hasta mis 22, cuando pude votar por primera vez, que me di cuenta de ellas.
