Yea I’m never sure why so many people are against this sentiment.
You get 1 vote every four years on an election issue which is often a red herring. There is legitimised if not legalised bribery of politicians. Politicians DONT have to be representative. The party can remove the guy you voted for if he actually keeps his promises. The parliament can be filibustered. The politicians don’t have to vote or read legislation. The parliament can be decided by niche whackadoos whenever there is a slim majority which is 90% of the time. Politicians and media are caught daily lying, porpagabdising and manipulating. Geographical Electorates can be manipulated to get whatever result the ruling party wants. The institution can pick and choose which votes they will count. You will be arrested if you exert the real power of the democratic process; protesting. The governemt monopolizes violence against you. Corporations buy their way out of everything. Socialized losses, privitised profits. There is no reasonable alternative beyond throwing your vote away and before you say preferential voting, I live in a country with preferential voting and it just makes things worse.
All representative democracies are sham democracies and that is all of them.
