Once you plant that seed, you start to say "there's too many politicians" and everybody nods and passively accept the cutting back on the number of people representing the public. (Looking at you Ontario PCs)

So then you have fewer politicians who thus have a lot more power and represent larger constituencies.

When you have a lot of power, and more constituents than you can possibly respond to, who are you going to pay attention to?

Donors and lobbyists.

So you end up fulfilling that prophecy because you become beholden to your donors and lobbyists who provide the money that help you convince voters that it's actually your opponent who is corrupt.

So my unpopular opintion is that we should have WAY MORE politicians, not fewer.
