My 2 cents...
I don't see the MEP thing truly increasing retirement plan creation. If somebody wants a plan now, I can find or create something pretty good. If they don't want a plan, I doubt whatever savings are available through a MEP are going to change their mind.
The RMD thing drives me up a wall! First, changing the table now and then is not going to make a significant difference, and is just one more thing to maintain and update for us. Second, if you don't want the money then, by definition, you don't need it for your retirement security. Third, if you don't buy the first two arguments, this overrides everything - YOU DON'T HAVE TO SPEND IT! You just have to be taxed on it. What is the big friggin' deal here?! You got a benefit from deferred taxation, and the RULES OF THE GAME have always been that you have to be taxed on it, later. This is just more conservative nonsense to minimize/avoid taxes (while we are looking at a trillion dollar deficit) couched in the image of helping poor Grandma, who is being "forced" to take money out of her retirement plan. It disgusts me, and I'm not exaggerating.
