There's an angle I'm not really seeing talked about - any wealth vehicle that allows the wealthy to defer their tax burden to a substantially later point in time creates massive incentive for those individuals to push for reduced taxation on that vehicle in the long-haul. It's one thing to want reduced taxes because it'll save you 8% on your %6M income each year, but another to want reduced taxes because it'll save you 8% on 30 years of deferred taxes.
