Although I don't think the person you're replying to is in the right. There are three branches of government, legislative, executive and judicial and replacing the legislators is probably the easiest out of all and the one that's going to bring the most benefit as well. I think your example is more akin to replacing people in the executive and people who generally "work the ropes" in government. Systemic corruption is very much a thing, but I think it's mostly concentrated in the legislative branch of government, than the executive or the judicial. I personally think it's easier to add to a system than remove from it, and maybe we ought to rethink the bicameral system for one that is more capable of representing the interests of the general population. Now, the real problem is that any changes to the system need to come from the system itself :) so there's obvious interests at play that might not be touched.
