> No chance 3 ever passes

It’s honestly the hardest one on there.

> a wealth tax would require an amendment

Genuine question, why?

> It would also be a bad idea to abolish the EC because then candidates would only ever campaign in cities

This doesn’t mathematically work. Most Americans live in suburbia. (We define “urban” very, very broadly for statistical purposes.)

And this effect is more than compensated for by the existence of the Senate and even House.

> it would complicate the recount process

No messier than now. And you’d only be delayed in close elections, in which case carefully recounting everywhere is fine.
