Hot take: All healthcare (physical and mental) should be free
Another thing to note is that a lot of the ultrarich evade taxes. Including business too. Just look at things like the panama or paradise papers for example.
+1 (the ultra rich and corporations should pay their fair share to the country and workers which provide things like the mail service, police protection, roads, etc. which they all rely/depend on.) not taxing stocks is a loophole that should be closed.
