Right. So you'd rather have them vote for a single candidate who sells them hopes and dreams that they'll make the right decisions to solve all their problems 4 years at a time, instead of voting for solutions to specific issues they're interested in where subject matter experts can actually improve things?
Corruption and greed are inescapable. At least by not giving a single person and party absolute power over everything, the damage can be contained to specific areas of government.

What's absurd is the current absolutist model that is easily corrupted via social media (Cambridge Analytica, etc.).
