Just limit the contribution that could be made to Roth IRA? We have a limit of $6000 CAD for TFSA (basically our version of the Roth here) across the board. And not a lot of Canadians make full use of this. I'm not saying what he's doing is illegal, but the article suggests that he jammed in enough eBay shares @$0.30 that when it was $19 per share, worth about $31.5M USD. So somehow he moved about 1.6M shares worth about half a mil? A yearly contribution room regardless of income would at least stop someone from stuffing lots of shares in a short time into Roth. It probably has the unintended consequences of being regressive to those who don't have the cash flow at all to make use of the Roth IRA.
