Well, not sure that I get what Unions have to do with voting rights of the teens.
Let me check what I said.;
.To some extent this was what used to happen in working Men's Clubs which Unions set up. People would get support there and a Political education. Unfortunately Thatcher got rid of most of our Unions which are a vital ingredient of Capitalism and not only did people lose the support but also the political education.
This is about how workers used to get an education on Politics. It isn't about the children so much as to say that we have lost this source of Political Education. The parents would get educated and educate their children. During that time we were a Social Democracy and I would say our Democracy was working well. However after Thatcher followed by Blair had introduced Neo Liberalism and allowed Monopolies - something which my parents generation would not tolerate, people started to feel their vote could do nothing to change the situation. I believe that one part of that was getting rid of Unions which are a necessity in a Capitalist Democracy to give the workers some rights. A few Unions still exist but in most places they are gone and so are the working men's clubs where they used to offer support and a political education.
The kids coming along now are not going to get any of that. I am not sure the age but lets say 35. People 35 and younger tend not to vote. They don't vote because they believe it will change nothing. To some extent I think today we probably do need a bit more but if they were to vote they would be able to get things because then Politicians would look to see what there needs were and try and bribe them to vote for them. At the moment it is the over 60's who are the most likely to vote and so who Politicians keep their eye on.
We want to get people back into politics again. That is why we are starting with the kids and helping them to learn how to go about it.
well that may well be going on as well.In my opinion, if you want the teens to be familiar with how democracy works, how to choose between candidates, what a voter can do to control their representatives etc. then it is better to implement the system of partial self-governance in high schools and colleges.
