One man, one vote. What's unjust about that?

Nothing. That's what we have now.


If more people live in
urban centres, shouldn't the interests of city-dwellers be given
proportionate influence?

Enhanced emphasis, perhaps, but not to the exclusion of the non-urban
population. The electoral college system gives us exactly that -- a
proportional level of influence -- since it is based to a large degree on
population. Since the system we have does what you want, why would you want
to change it?
