Assets doesn’t really mean much unless he sells it all.
Plus he’s a fool who has a tendency to get into flame wars on twitter that make him look even more foolish.
Wouldn’t you love to be Trump’s campaign manager? The Donald has an ego that’s even bigger than his declared assets. I predict Trump will go through two or three managers before he finally fades in the primaries. Still, I’d pay to see a debate between Trump and Hillary as they declare themselves saviors of the middle class.
Assets also don't mean much until you take into account liabilities. He might just have some mortgages/bonds/debt associated with some of his properties.
