Almost every problem in the world would be dealt with meaningfully if we outlawed billionaires.
Everytime I look at small problems or big global problems, if you follow the money trail, it all leads to some billionaire who is either working towards increasing their wealth or protecting their wealth from decreasing.
Everything from politics, climate change, workers rights, democratic government, technology, land rights, human rights can all be rendered down to people fighting another group of people who defend the rights of a billionaire to keep their wealth or to expand their control.
If humanity got rid of or outlawed the notion of any one individual owning far too much money than they could ever possibly spend in a lifetime, we could free up so much wealth and energy to do other things like save ourselves from climate change.
In the US we used to have a very high tax rate for those who were extremely wealthy, Distributing the excess back to the government/citizenry. We need the return back to that.
The citizenry need to ask for that, as well as for ranked-choice voting.
As far as voting is concerned everyone who is eligible to vote should get one vote. It is a terrible idea to do anything other than that.
As far as taxes go, we should simply encourage people who are wealthy to fund charities. Also the tax rate is already pretty high. Maybe we just need to increase the number of rungs on the scale. I don't think millionaires or billionaires have anything against taxes or at least nothing compared to the rest of us.
You should look into ranked voting. You still only get one vote, just if your preferred candidate is eliminated you can propose your second/third choice as well. This allows you to vote with your morals but also strategically.
The problem exists, but I do wonder if the average voter can understand it. We have a lot of difficulty getting average people to understand basic concepts.
"Oh wow so undemocratic holy shit you psycho how dare you even suggest a thing?"
Two party system?
"Oh woooow so much democracy everyone gets to choose between two options. Perfection achieved. Aliens cross the galaxy to study our high advanced flaeless two party system in a desperate hope to emulate it"
More then two parties?
"No way there should be more options, that's just crazy you psycho how dare you suggest this to me just shut the fuck up and vote for the blue conservatives."
I hope some day you think outside the box. More like a prison then a box really...
