Mine are 3, 5 and 7. If mine could vote, they would vote for getting rid of coal plants and gasoline engines. They would vote for stopping commercial fishing and chemical dumping near places where people enjoy the water and beaches. They would vote for mandatory recycling of plastic, and reduction of use in plastic throughout society. They would make those laws absolutely vicious in enforcement, if I can extrapolate from my brief conversations with them about these topics.
They would vote for doubling of social security benefits for grandparents that hung out with their grandkids.
They would also vote for guaranteed daily movie rights for children, unlimited Harry Potter legos and mandatory one-Wii-per-child laws.
At any rate. The article suggested parents wielding the vote on behalf of children in Japan as a way to have a say in an aging population, so we are now well off topic from HN's core goals.
