I’d disagree with that one. We have limits on lobbying and fundraising etc. I’m sure you have “safe seats” as well, where the constituents almost alway vote for the same party whoever they nominate. Just as the USA has a few states that ultimately decide Presidential elections, we have a few seats (I’d say about 10-20) that decide Federal elections here. Basically in any democracy, the best places for government services are those that decide elections.
People just voting out of habit get taken for granted. All governments need to be tossed out very 2-3 elections, otherwise they just get complacent and take governing for granted.
Plus, I do know a bit about the historical origin of the term “gerrymander”. Pretty sure it was a Mass Governor, wasn’t it? Massachusets wasn’t it? (I was brave in my attempt at spelling but failed).
