Goldman Sachs is never in trouble. They are far to connected. Your 401k will be taken from you before Goldman Sachs has catastrophic troubles allowed to kill them.
Quite possible. They are one of the Heads of the Five Families though I think the names may have changed over the years.
Goldman Sachs, JP Morgan, Citigroup, Morgan Stanley and Bank of America.
I might be wrong though. That’s off the top of my head.
