a tax giveaway and here we are in the united states. give us a history lesson here. how did south dakota become essentially one of the world's great tax havens? >> well, south dakota's secret sauce is that they don't disclose who the beneficiaries are of the trust. secondly, they don't charge any taxes, income tax or taxes on the trust assets. and the third important ingredient is you can have a perpetual trust in south dakota. starting in 1983, the trust industry went to the state and they changed the laws to eliminate a provision of property law that basically says a trust has to wind down within a generation or two. those three components basically make south dakota a real destination and attraction for what we call dynasty trusts, people who want to park and sequester billions of dollars forever.
