Lots of money parked in the 401k's.
It was a tax haven of sorts.
Now record numbers of 35 to 55 Year olds are taking hardship withdrawals.
Are they taxed (don't know). If not it might be a great time to find the excuse to take these withdrawals.
This is big stuff, really big. Soon 401K holders/contributer may be forced to buy T-bills (after Big Ben is done talking them down).
