Biggest reason that 16 year old shouldn't vote; they don't support themselves

Very few 16 year olds are supporting themselves.  Hence they don't suffer if they vote in candidates who massively raise taxes and destroy the economy.

They have no skin in the game so to speak.

We vote to decide how we are to be governed and 16 year olds are primarily governed by their parents or legal guardians not the government.  So 16 year olds who are being supported by someone else shouldn't have a say in how the government impacts everyone else.
