Talking about being able to ride a bus in the US is comical.
Depends where you live. It’s much more doable in the densest urban areas than it is somewhere rural. I have a friend who lives in Boston for example and he doesn’t have a car, at all. Because Boston’s mass transit is good enough for his routine needs. I can’t do that here, however.
No, no, no. Just like a tax on unrealized gains is a bad idea because of how much it would royally fuck up the stock market, including every 401(k). What they need to do instead is tax the ways used by the extremely wealthy to utilize their gains without technically realizing them, even if that sometimes means taxing debt (aka treating it as income when they borrow against it and taxing accordingly).
Citizens United didn’t make corporations people. Corporate personhood had been a thing for a very long time, largely about whether or not forming a business means you lose legal rights operating under it (Does a business entity have freedom of speech? What does freedom of the press even mean in an 18th century context if it doesn’t apply to a business [aka a newspaper]?) and whether or not regular old laws prohibiting a person from doing a thing can be applied to businesses.
