I am in my early 50’s. House is paid off several years ago. No debt at all. The 401K has no provision for collapse. Best is money market, but that could be wiped out by inflation or govt seisure of retirement accounts. I have some IRA and Roth funds that could be moved into gold or real estate investments. I could quit my job so I can get control of my 401K. I think I could retire easily.
Nothing like a money market fund for those oh so safe credit default swaps.
Good luck with any planning for a “doomsday” scenario. The problem there is that a major collapse would have ripple effects that may not be anticipated — which means even your “doomsday” investments aren’t any good, either.
