I don’t personally, but it is another proposal, that’s why I mentioned it. There are some parts that seek decent but I have not read up on full explanations enough to understand the theory behind it.

There are many better proposals

You literally claimed there are "many better" proposals, and listed two... One of which you yourself don't agree with, but only listed because "it's another proposal"? That's not a proposed better system, that's a red herring.

but how does a greedy person then get elected?

The same way they always have? They run for office and people vote them in? Do you think anyone in Ohio actually thought this guy was going to take 60 million in bribes?

Why aren't people removed currently when a majority of the country seems to agree a lot of politicians that are in Washington shouldn't be?

As for government and democratic improvements, since I’m assuming we are comparing against the US, we have a pretty shitty democratic structure and even governmental structure to some extent. First and foremost, the two party system and first past the post voting. Systems like ranked choice allow for a much broader set of parties and corresponding values to be expressed in governance. Other things like how shit of an institution the Supreme Court is, the electoral college, etc. A more European democratic model is much better.

Sure, but these same improvements could be made to our current system; why can't we even get that done?

And on top of that, the workers being in control will eliminate a lot of the motivations for businesses to do ‘bad’ things. Treatment of workers and profit distribution most obviously, but also things like quality of product or service, because the workers are also likely either direct consumers of it as well or more closely linked to direct consumers.

[needs citation]; genuinely not to be rude, but this is literally the same spiel everyone that's anti-capitalist gives. It's nothing of substance, it's entirely unproven. Even assuming it's true, you must assumes that you'll even be able to put and then keep the workers in power. Also, which workers, all the workers? Representatives for the workers? etc. That's a lot to take for granted.
