That's not how I read the article at all. Honestly how I read it shows how he was able to abuse the system in ways that weren't intended. It also lays out clear and simple solutions:

- Only let publicly traded stocks/investments be part of an IRA

- Stock grants should be included in the maximal income to determine if someone should be able to contribute to an IRA

Honestly with just these two factors he couldn't have done what he did (implicitly nor anyone else with mega IRAs). The intent of the IRA was for a retirement vehicle for the average person, not as an investment vehicle where you could dodge taxes. You're right that he didn't commit any crimes. But that also doesn't make the thing right. When we find people using edge cases and breaking the intent of the system we say "well played" then patch the framework.

This is a tax dodge, just a legal one.
