That must be a nice problem to have. Realistically this probably doesn't hit many people, and the ones it does hit already afford accountants who conjure up ways to minimize their taxes. Yea, I know, this is HN, where everyone knows that buddy who's cousin's roommate makes $400K at Google. The average geek doesn't have to worry about this.
The Roth phaseout starts at $117k for single earners. That is a lot of money, more than most people in the US, let alone the world, make, but it is not a princely sum for most technologists, especially not ones on HN.
