Recently read "Power of Zero" where the author (David McKnight) makes a pretty compelling case to move 401K/retirement investments to better tax advantaged investments due to likely tax implications. We are in a period of fairly low taxes; pretty good bet taxes will increase in the future. Not sure it truly is possible to shield all retirement assets from taxes, but a decent strategy to minimize impact as much as possible. Not sure how long some of the current tax advantaged options will remain available/viable, but diversification of tax implications warrant examination.
