It turns out, Donald Trump only "owns" five buildings. He has minor interests in others, and other businesses, but nothing close to a controlling interest.

[R]ecognizing that Trump’s big borrowings are concentrated on just five properties raises a nettlesome question about the mogul’s epic claims. In reality, Trump owns, or owns portions of, just a few major properties, though what he does own are trophies. If you take a reasonable estimate of the value of his holdings, and put a likely multiple around 15 on his recurring royalty profits, you don’t get too far over $4 billion. Subtract $1.11 billion in debt, and you’re somewhere in the $3 billion range as Fortune previously estimated.
5 Things You Need to Know About Donald Trump's Debt.

Here's the thing, and this will shock absolutely no one: Trump lies about everything. Not "waffle", not "shade the truth" - flat out lies. Makes stuff up. Promotes stuff he knows to be false. He doesn't go a day, or a topic, without lying. His "worth" he has lied about so often it is hard to keep up with, and even he may no longer know the truth (but I bet his accountants do!). The rough formula Fortune used to use is "divide by 3" - take whatever he "claims" and divide it - and that worked for some time. I'm not sure it does anymore, but who knows? If he released his tax records, maybe we'd know. But, then we'd know. If there is one thing Donald hates it is getting caught in a lie, and that happens so often. Then he'll move on to the next one.

A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
