As you can see, Trump is in hock to a veritable who's who of Wall Street banks, as one would probably expect of a person who makes a good portion of his living doing New York City real estate deals. The bare minimum amount displayed here is at least $250 million in loans, although of course it is probably much, much more than that. Trump has four loans listed here that are "over $50 million" and of course, those might go all the way up to a billion each or beyond.
Now, no one knows how much Trump is worth, and his own word is definitely not to be believed on that subject, but it is clear that some very significant amount of it is tied up as collateral for these loans. Nor would it really matter if Trump announced he were going to pay these all back tomorrow, at least by his standard.
I would frankly be surprised if someone of Trump's business profile has not at one time had an enormous outstanding loan from every bank of any decent size in the country, in fact.
If Ted Cruz is owned by Goldman Sachs and Citibank because they once gave him a $1 million loan (even though it is completely or mostly paid back), then Donald Trump is definitely owned by not only Citibank and Goldman Sachs, but also by every name on this list.
If America can't trust Ted Cruz to protect them from Goldman and Citibank (although why any of us need protecting from Citibank, I do not know), then how can anyone in America trust Donald Trump to protect them from literally every bank?
As for Goldman Sachs, Trump is himself a shareholder in Goldman Sachs, which means he has a direct financial interest in its success. One would think that would make Trump even less enthusiastic about protecting me from Goldman Sachs (whatever that means) than Cruz would.
