Imagine you run a business which makes 1,000,000 per year. Your operational cost run you 66%. You have 33% you use for growth. You have a nice little plan, but you want it to grow faster. You decide to mortgage some of the equity and assets to fund your growth. So, you barrow 1,000,000 dollars which cost you 100,000 per year. No problem you increase your business by 10% so you can cover the cost of your loan. Your plan works out great. Only one problem, you only appear to be wealthier. In actuality, you are worth less now than one year ago. You find yourself discontent with what your company is doing so you use the same process the next year, then the next, and so on. You are growing larger and larger. Now you are not as lean as you once were so your operational cost has increased to 80% and then the unimaginable happens. You stopped increasing revenue to cover your cost and your previous loans. This is a scenario which is repeated everyday. This is a corporation killer. When you see a once mighty corp sell out like Dell for pennies on the dollar this is what causes it. The only thing in the case of the WBTS no one will buy them out.
This is all hypothetical, but they are acting like a corp which has cut its own throat. Just because one sells a building for a billion doesn't mean the money goes to the seller. The bank always gets it's cut first.
