Assuming billionaires were going to get a special tax, how would you actually determine how much to tax them? Sure some would be straightforward like Musk where it’s entirely derived from a few companies with known ownership stakes, but what about all the others?
We don’t even know the names of most of the billionaires. With all the games they can play to hide money, now made even easier thanks to the changes Trump made in his first few months, how would you even figure out who and what amount to tax? They don’t have a normal salary or easily documented income like everyone else.
5% wealth tax, and no loans for corpos or other orgs, only for humans and even then it would be considered a charity (meaning if they default money goes puff), this would mostly be coming from tax that was collected earlier.
Also no patents, only open source research. So people can set up bussinesses easily and anywhere, buyers will pay for labour.
We already know how to grow food and build houses, let’s end these issues first and only then focus on advancing science and tech, and any advancement should be for betterment of all humanity, not for individualistic gains.
