I had just about the same reaction when I found out the same thing last year! What a horrible, painful discovery! I've switched to Vanguard, too, and haven't looked back. I feel like this should be made more obvious to the general public! Teach it in high school! Put it on billboards! Whatever it takes! (I know, I know. I'm sure it was on a form I signed somewhere.) I'm just glad I realized it now and not much later in life. Same for you... better late than never.
And I agree... fantastic advice, perspectives, ideas, etc. here.
