Yes, any citizen that pays taxes should be allowed to vote

If you financially contribute to a country you should be allowed to have a say in how that money is spent i.e. by choosing the party that aligns most with your beliefs.

nobody under the age of 18 is earning enough to pay taxes or paying taxes of a decent rate. This is a weird question because why does taxes have anything to do with who or what age should be allowed to vote? It’s absolutely irrelevant.

If you are contributing to public funds and national insurance, you have a right to have a say in where that money is going, regardless of age.
