He bought paypal stock privately when it was almost worthless, which the roth ira allowed, then the stock exploded.
I mean, sure, if you can tell the future you can do what Peter did.
I don't have an axe to grind against him or what he did to be clear.
My point is that he bought private stock, something that is privileged, so it's not entirely accurate to say that all people benefit from a roth IRA equally.
I personally don't think that the average person has the ability to take similar advantage, even though they both have the same limitations on paper.
