If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
a) there's a persistent market distortion because investment profits are undertaxed
b) savers are often not terribly price-sensitive; a lot of people will "save as much as they can" at any interest rate. Also interest can't go below nominal zero (many bank accounts are very close to this).
What do you mean? Corporate tax rates, at least in the US, are higher than personal tax rates.
