He just spend 400 million dollars on the election, half of this in texas alone.

But anyway, I don't think it's fair to say he "hoarded" wealth. It's all from ownership in companies he led, or selling stock in said companies. It's not like, I don't know, post-soviet Russian oligarchs or Carlos Slim or something, who you could all reasonably say were hoarding wealth.
