Assume the government is about to enact a fairly serious bit of legislation, but they call upon a referendum. (For example, the upcoming 2017 referendum regarding membership in the EU for the UK). Considering it'll impact the younger citizens of the electorate more than the old, in the long run, should the worth of votes be proportional to age brackets? As a system of implementation, there are polling systems and stations made specifically for that age range, and you must present identification before casting your ballot.
