Exactly, Gross worth is meaningless. If you have 500 million in cash and assets, but you owe 1.5 billion, you are not rich, you are worse than broke. The average person living in the shelter is better off than you.
Edited to change stupid math error.
Well
If you owe the bank $1000 and can't pay it back, you have a problem.
If you owe the bank a million and can't pay it back, the bank has a problem.
If you owe 1.5 billion Whoever gave you the 1.5 billion can't go after the 500 million, because if anyone notices, he will lose his job.
