Yes, we should change the system. It was a compromise that is now well outdated.
The EC was more than a compromise, it was an integral part of a system that prevents too much power being handed to any one institution or demographic. And forcing national candidates to appeal to a multitude of states rather than a handful of cities has a moderating effect.
If anything, what's outdated about the EC is we need more checks on the political influence that is centralized in cities because the founders didn't anticipate urbanization.
