> This country has been around for over 200 years. Our elections have worked well, or else we wouldn't be having this conversation.

Doesn't follow; countries can exist for a long time without elections at all, and, a fortiori, without elections that “work well”. Our existence and ability to debate th topic doesn't prove our elections worked well on average over history, or that they've been working well in their most recent form. Or much of anything else.
