Because working with direct supervision is a far cry from making decisions that affect everyone.

I have a 16yo, bless her heart. No way is she ready to vote. I’d far rather not tax children than give them access to running anything connected to law.

Part of the reason 18yos are “ready” to vote is they ostensibly have a couple years of working under their belt. 16yo have no idea how disconnected from reality they really are. Give them a couple more years to operate under responsibilities, first.
