Why should we vote?

The question on everyone's mind is "why should we vote?"
When a large % of an age group votes, they usually end up with all the
benefits. Take for instance people who are ages 65 and above. They are the group
that votes the most. They recieve benefits in Medicare.
Does youth recieve any such thing? Do they get almost every medical expense paid for?
I did not think so. So if we, as youths, want increased benefits, then we have to tell the politicians in the polls.
